Replace discus ? Selection, comp.
9/6/19
Hi Team,
<Shriram>
Trust you guys a doing well.
<Thank you; yes; well enough>
Recently my canister started to leak in the middle of the week and I had
to make alternate arrangements for my 50 gallon discus tank, until I fix
it this weekend.
In the process I lost few of my guys, and now I have two big discus who
are the leaders and a few 4 smaller ones, out of which one of them seems
to be quite timid and likes to hide behind the rock and comes out very
rarely and is not very active when it comes to food.
Now I have a few questions.
Is it a rule that you need to keep discus of the same size for a good
bonding.
<Mmm; well, close to same size is a good idea. IF too different and
there are "problems", in small enough volumes (less than hundreds of
gallons), the larger one can/may damage the smaller>
In that case do I need to replace my bigger ones for ones of smaller
size, so my hiding discus gets normal.
<May be; or move all to a larger system>
Odd One Out.
What is your suggestion in replacing my discus and move on to a set of
monster fish as in: Oscars, walking catfish, etc. I understand this is a
question of personal preference, but do you think its easier to maintain
the monsters and that they would not need filtration like the discus
need, and still look good in the tank.
<Yes to other fish species being more "poor water tolerant", but they
will still require robust filtration, water movement, frequent (weekly)
partial water changes. Bob Fenner>
Please advise.
Thanks and regards,
Shriram Natarajan
Female Discus chases all Males.
3/14/19
Hi Mate,
<Shri>
I have a scenario in my tank. One of the Female Discus (who is the Queen
of the Tank) keeps chasing the Blue diamond males (Both small and big
ones).
He does not seem to disturb the other pair.
In total I have:
Males: 4 (2 small Blue diamond, 1 Big blue diamond and 1 with green and
blue patterns))
Females: 4 ( 1 Green and Blue pattern, 1 big with blue dots, 1 big with
blue patterns and 1 small yellow).
Sorry for the rough description.
Please suggest what would be the correct ratio and what changes should I
be doing to have the right ratio.
<Mmm; more really has to do w/ the amount of space/room for all... such
that they can form pairs, engage in tolerable fighting (with enough area
to get away; avoid further pummeling). Sex ratios of about 1:1 are fine.
IF one or more fish are getting "too beat"... as evidenced by darkening,
hanging out at an angle, in corners, the surface; it is best to
immediately move the one doing the damage elsewhere.>
Waiting for your response as always.
Thanks and regards,
Shriram Natarajan
<Welcome. Bob Fenner>
Discus Aggression 2/28/19
Hi Crew,
<Hello!>
I recently came to know that that WWM crew works out of time to respond to the
high email traffic you guys get and run the site. YOU GUYS ARE DOING A GREAT JOB
by providing sensible and practical advise to the fish keeping fraternity.
<Thanks for the kind words.>
I am sure I have dropped in many annoying emails to you guys and I keep checking
my mail waiting for your response.��
<Sure thing.>
Here is my question for today.
I have 3 pairs of discus in my tank out of which 2 are bigger in size and the
other 4 are smaller. Out of the 4 2 are blue diamond which seem to be more timid
and of the weaker section.
<Can happen. All the artificial varieties are inbred, and a rule, the more
extreme the variety compared to the wild fish, the more inbreeding has happened.
Consequently things like genetic diseases, poor growth rate, inept breeding
behaviour, and overall lack of vigour can be commonly seen in such varieties.
Not always for sure, and farmed Discus are generally easier to keep than
wild-caught specimens. But there's a fine line between breeding fish to favour a
particular colour pattern and inbreeding them so much they're demonstrably
weaker than the more genetically mixed wild-looking (rather than wild-caught)
Discus.>
I observed recently that one of the bigger discus seems to chasing the blue
diamonds every time they try to come out to the open. This bigger guy seems to
only like to chase the blue diamonds alone. He doesn't seem to disturb the other
smaller pair. This has led to the blue diamond to hide and stop eating. I would
like to know if adding another pair of smaller discus would reduce the
aggression or do I need to add a pair of bigger discus to divert the bully.
<It's a challenge. Yes, usually adding extra specimens reduces bullying. So
often people keep Discus in large groups, 8-12 specimens, if they want to keep a
school of them. Bear in mind that wild fish only school together outside of
breeding, so it's entirely normal for them to form territorial pairs once
breeding.>
The count of my discus (3 pairs) is it a good number or are any changes
required. My tank should be around 50 gallons
<Here's part of the problem. A pair of Discus will hold a territory with a
radius around 30-45 cm around their egg-laying rock or whatever. So you really
need to allow a circle maybe 60-90 cm in diameter for each mated pair, and any
extra Discus will be chased away if they get into that patch. Realistically,
you're not going to be able to have that sort of space in a 50-gallon tank.
You'd do rather better keeping a single pair, perhaps alongside suitable dither
fish (Silver Hatchetfish, Rummynose Tetras and Cardinals are classic choices)
and bottom dwelling catfish (Corydoras sterbai is the definitive catfish for
Discus set-ups). I doubt additional Discus will be tolerated for long in a tank
this size.>
Waiting for your advise as always.
Regards,
Shriram
<Hope this helps, Neale.>
Sick discus need help 5/19/18
Hey ! My discus fish is not eating since 3days after the death of his
tank mate and today he has clamped its fin.....and is in stress
<Yes, probably is stressed. May well be suffering from whatever killed
the other Discus in your tank. Review the conditions in the aquarium. To
recap, Discus need a large tank (for a pair, probably over 150 litres/40
US gallons) and certainly need good quality water with the right water
chemistry. In other words, 0 ammonia, 0 nitrite, and a nitrate level
below 20 mg/l. Water chemistry should be relatively soft for farmed
Discus: 1-12 degrees dH, pH 6-7.5. Wild-caught Discus are more fussy,
and must have very
soft water, more like 1-5 degrees dH, pH 6-6.5. Water temperature should
be relatively high, 28-30 degrees C. Discus are omnivorous in the wild,
and need a varied diet in captivity. They are prone to Hexamita and
Hole-in-the-Head diseases though, both of which are more likely if they
are given monotonous, low-vitamin diets lacking fresh greens; cooked
peas, for example, are usually eaten by hungry Discus without too much
fuss. Cheers, Neale.>
Discus Food
3/5/18
Hi Team,
<Shiriam>
I have a Discus along with some Angels.
<Do see/read on WWM re both fish's compatibility; not good to mix these two cichlids>
I feed my fish with Tetra Bits (sinking pellets).
<Discus/Symphysodon don't generally eat pellets with any gusto. READ:
http://www.wetwebmedia.com/fwsubwebindex/discusfdgfaqs.htm
My Angels like the sinking pellets and eat them as soon as it is dropped into
the tank. My discus is comparatively smaller in size and doesn't seem to eat or
like the pellets. The lfs from whom I got, told me that he used to feed live
worms to the discus and asked me to continue feeding the same till the Discus
grew in size.
<Pretty standard; yes>
I am unable to find time to feed the Discus with live worms every alternate day.
I usually feed my fish live worms on weekends.
Please advise what should I be doing to make the discus eat the pellets.
<Reading. Bob Fenner>
Thanks and regards,
Shriram Natarajan
Discus Keeping Inquiry 4/23/15
Dear WWM Crew,
<Megan>
As has been echoed by your plethora of followers, thank you for having the best
fish-keeping website on the internet. Having an English Lit background, I'm also
appreciative of your stinginess with grammar...
<Indication of respect; but also functional necessity for search tools to work>
although now I'm terribly nervous to write you an email (does fish-keeping have
a dash???).
<Heeee! Does>
Despite being a relative novice at the hobby (I have two smallish tanks set up
at the moment), I'd love to try my hand at keeping discus. I've heavily
researched this topic, and I think I've been through most of your website's
content on the species. I'm still a bit nervous, however, having not kept
non-hardy divas before.
<Symphysodon are quite tough nowayears... though still need some basic tools,
care>
I'm having a bit of a tank size/number of fish dilemma, and I wondered if you
may be able to help me with that, and if I could run past my hypothetical set-up
with you (run-on sentence??? Ack!).
<No worries>
I live in rural Newfoundland, Canada, and being in such an underpopulated area,
have a somewhat limited selection of tanks which can be sent here. I have my eye
on the ADA 295 L tank which measures (in cm) W120xD45xH60, and I can even have
this sent to the wilderness where I live. The dealer tells me this equates to 86
gallons, although my computer tells me 295 L = 77 US gallons/64 imperial
gallons. Am I missing something here? (Maybe I'm too dim for fish-keeping).
<Your calculation is closest; about 78 US gal.s>
Taking your advice regarding number of fish, I'd like to have a group of minimum
6 (I'm thinking of purchasing tank-bred adolescent blue diamonds).
The advice on #fish/gallon seems a bit divided, ranging from 10-30 gallons per
fish. I'm also unsure whether this is US or UK gallons. At any rate, do you
think 6 individuals would be OK in the tank described above, keeping in mind I'd
like this to be their permanent home?
<Yes; you may find it expedient to separate paired couples in time... easier for
keeping the peace during reproductive and rearing events>
If the tank is in reality 64 gallons, perhaps this is too tight for 6 adults?
<Mmm; six is a good number to have, start here>
I'd like to have a gravel/river rock bottom, with some silk or soft plastic
plants for hiding spots (this sound OK?).
<Yes>
In this area we have very soft tap water, pH of 6.2-7.2, so I think that will
work out well. I'm aiming to introduce the fish to a properly cycled tank, keep
the temperature at 82 F, with frequent large water changes, as I've read is best
for these fish. I
have a quiet, dim part of the house I'm considering for the tank. I thought I'd
use an Eheim cylinder filter, as Neale advises.
<A good choice>
I'd like to include a school of glow tetras and another of penguin tetras, if
you think that would work well?
<Yes; with size they Symphysodon may consume the Tetras>
Would you advise me on the size approximate size of schools of these fish for
the tank described above?
<Several of each... like a dozen or more>
Any other advice you think a newbie should hear in my situation also greatly
appreciated.
<Perhaps an easygoing smaller/mid-size Suckermouth catfish... like of the genus
Scobinancistrus, Ancistrus...>
Many thanks for your generous advice from an eager, possibly overly anxious,
potential discus-keeper.
Kind Regards,
Megan

Hi Alesia,
<BobF at your service>
I want to set up a planted Discus tank. I have been reading a lot
of articles online and when I read one of your articles I determined you
are the one that makes the most sense. I want to be prepared to
succeed.
I have had many aquariums and have kept Discus successfully but never a
planted Discus tank. Two years ago I had to sell 11 Discus I
had for two years in a bare bottom tank because I went to Iraq for six
months.
I plan to set up a 90 gallon tank with a few varieties of green plants
and a dozen of 3 to 4 inch Discus from Discus Hans.
I would appreciate your guidance, please provide reading material,
preferably written by you.
Thank you for your time and consideration.

BGK/Discus... rdg.
2/27/12
Hello,
Unfortunately I had to euthanize my Oscar the other day. The poor
guy was getting worse every day and I couldn't stand to see him
like that anymore.
So today I had the exciting task of selecting the next generation of
fish for my 55. I decided that ultimately I would like to have a Black
Ghost Knife and Discus tank. What are your recommendations for
this system in regards to size of the tank and quantity of discus.
<Already posted, archived on the WWM site. Search, read
there>
I currently also have a Plec in there who is about 2 years
old.
<Which species? May not be appropriate for use with these
others>
I got the BGK yesterday and, being the only other fish the
tank, has been happily swimming over every inch of the tank.
I've never seen one so quick to explore. The ghost knife is
very small (3") and I am wondering if I should grow him out a bit
before adding the discus. I don't mind getting rid of the
Plec if it comes down to it because of temperament or space but I do
hope he works well in this system, however, keeping him does mean I
would have to forgo live plants which I would very much like to include
in this system. I currently have a Marineland canister filter
rated for 100 gallons and multiple powerheads to create a
current for the bgk, also NO2, NO3, ammonia are 0,
<No nitrate? How rendered thus?>
pH is 7 temp is 76-77
<Too low for most Symphysodon>
and I brought home wet frozen bloodworms and brine shrimp. Does
this sound like a workable tank?
<Not yet>
Should I grow out BGK? How long would you recommend keeping
these fish in the 55 as juveniles (I plan on upgrading to at least a 90
w/in a year)?
How many discus would you recommend for best results? Thank you for all
your help.

discus problem 4/26/11
Hi
WWM Crew
<Amit>
I have a problem with my youngest discus. He is approx 1.5 inch. I have
observed that he has turned black and mostly hiding and not accepting
the food as he used to do, he will just nibble a pellet . His gills
have become red .His fins and tail are also stuck together, I mean they
are not erect like they used to be.
<Very bad signs/behaviors>
I am really worried bout my discus. could you suggest me the treatment
for the problem
thanks in advance\

Re discus problem... didn't read
4/27/11
Hi
WWM Crew
<Amit... you didn't read where I referred you to
yesterday>
I have a 25 gallon tank. I have 3young discuss and 2 Danios, <Not
compatible... chemically, temperature wise...>
2 black neon tetra. I am using a corner filter. I do 20 percent water
change after every 3 days. I feed Tetrabits to my fish.
<Not suitable for Symphysodon>
I am based in India so the ambient water temperature during summer is
30 degrees.
I have recently observed that my fishes rub their body against the
corner filter and some rocks which I have kept. I use a bare bottom
tank. There are no signs of white spots on their bodies. They are
eating properly.
I have added 2 tablespoons of rock salt to the tank water.
<...>
I wanted to know whether I can use rock salt for my discus tank and
whether there is any other treatment to get rid of the problem

Discus questions... ID, fdg., beh.... gen.
2/20/09 Hi crew, sorry to bother you again? However, i
have 3 discuses, that i got 1 week ago, in a 40 gallon tank and 1
of them (the orange discus) only eats bloodworms. I try feeding
flakes and brine shrimp but she/he showed no interest. The other
two eats everything. How do i teach the orange discus to eat
different types of foods? The dominant discus does bully both of
them, but i don't know if it is temporarily because i just
got them. Does the bullying effect what they eat, because when i
feed bloodworms, the orange one goes crazy. They all seem pretty
healthy. Here are some pics of them. And do you know what type
they are? thanks
http://s724.photobucket.com/albums/ww244/fish111111/?action=view¤t=DSC02493.jpg
http://s724.photobucket.com/albums/ww244/fish111111/?action=view¤t=DSC02486.jpg
http://s724.photobucket.com/albums/ww244/fish111111/?action=view¤t=DSC02490.jpg
the dominant discus is the red and blue one. Thanks for all your
help. <Hello Chris. I'm not expert on the types of Discus,
and so far as I can tell these are standard Symphysodon hybrids
of the type widely sold today. So I can't help you on that
topic. As for diet, Discus tend to be finicky, and the golden
rule is to feed as many different things as possible. Live
daphnia, bloodworms, mosquito larvae, and small earthworms are
appreciated by all specimens. I'd avoid freeze-dried foods as
much as possible, but good quality flake foods are certainly
taken by some Discus. By all means try different brands: many of
my fish will eat one brand but ignore another! Hikari foods tend
to be the best and most widely accepted. Now, as for social
behaviour, Discus are best kept either in matched pairs of groups
of 6+. Your trio WILL have problems with bullying, as you're
observing. Like Angelfish, Discus are schooling fish when young,
but territorial pair-forming fish as adults, so unless
they're in a big group, pairs will pick on singletons. So
either get rid of one, or buy three more. If you keep six,
you'll need a bigger tank. Your move. Cheers, Neale.>

Re: discus questions 2/20/09 Hi
Neale, thanks for the reply. Is it possible to keep four discus,
will that help at all? <Not really Discus, Angelfish and
Festivums all fall into this "either a pair or six"
category Of course if you kept four females, they'd be fine,
but you can't sex Symphysodon so unless you're able to
split mature (i.e., spawning) pairs, getting six females isn't
practical.> What is the maximum number of discus i can put in a
40 gallon (adults). <A matched pair.> My discuses don't
pair up to bully one of them. <No, perhaps not, but the bully
could easily be a dominant male and the bullied fish either another
male (or, less probably) an unresponsive female.> There is only
one dominant discus that picks on both of them. <Quite.> Will
this be permanent or is he just establishing the pecking order?
<Impossible to say. The best you can say is that the
overwhelming experience of Discus keepers is that 3, 4 or 5 adults
don't tend to get along. A single male and three females
probably would, but there's no way to guarantee you'd get
that ratio. Two males would bicker all the time, and one would end
up being bullied. Eventually, it would have to be removed.> How
long does it take to establish this in general. <May not do
so.> They are also extremely scared whenever i walk by them.
<Quite normal. This is why Discus are kept in groups in display
tanks. When kept in groups of 6+, they are much more secure and
likely to swim about normally. The addition of calm dither fish,
such as Silver Hatchetfish, can help, but this assumes your
aquarium has sufficient space for all.> I tried to hand feed
them to show i am a source of food, but i don't believe that
helped much. Last, what is the nutritional value of bloodworms, are
they considered healthy or treats? <Healthy.> Can it be used
as a staple diet? <A fair staple diet, but do augment with
pellets, daphnia, etc., once or twice a week.> I will continue
to try to add variety into their diets, but since they aren't
eating anything but bloodworms, should i lay off them or continue,
as i don't want them to starve. <Variety is central.
Experiment, switch between brands, raid the kitchen for small bits
of seafood and white fish.> Thanks so much Neale, i appreciate
your time. ~Chris <Happy to help, Neale.> re: discus
questions thanks for your help, i will upgrade to a 60
gallon soon <Probably very wise. Get six juveniles for now, and
once they get about 8 cm/3 inches in length, they'll be ready
for a bigger tank. Much written about these very special fish;
would highly recommend spending a little time browsing WWM and your
local bookstore, library, or online book retailer. Cheers,
Neale.> |

Bleher's New Discus Tome! 9/22/06 Dear Mr.
Fenner, <Heiko? Of Aqua-Geo...?> my name is Heiko Bleher,
and I do not know if you have heard of my name, but possibly. In
any event, I have been collecting wild discus (and other aquarium
fishes) since I was 8 years old (with my mother, Amanda Bleher),
this was 1953... <Yes, know a few anecdotes re your
"Bleher-Mobile", your extensive adventures... you and I
have chatted a couple of times... casually, at the Interzoo shows
over the years. Hello to you> The reason I am writing to you,
is about my new book: BLEHER´S DISCUS which I think you
should also have in your library. <Oh!?> I wanted to let
you know, that this volume 1, on wild discus, just came off the
press. It is an outstanding Monograph of the genus Symphysodon,
as never done before. A work that has more than 670 pages, over
3000 photos, maps and paintings, 380 different wild discus with
its precise location, and over 380 - in part new - Amazon fishes.
<Great!> It contains 250 Discus-habitats throughout
Amazonia with its parametres and detailed biotope explanation.
There are 80plus pages only on discus nutrition in nature, with
each component - the result of hundreds of stomachs and guts
researched immediately after collecting. The book includes the
entire Amazon-history of discoveries, its explorers and their
scope, the Indian tribes of past and present (their status today,
cultures of past and today's), the status of almost every
Amazon city and village today. This book is a must for every
Discus enthusiast, every fish-lover and every nature and (or)
Amazon (fish) lover. Sting as well as Leonardo de
Caprio just got their copy signed. <Heeee!> Have also a
look at the attached review, which was just published a few days
ago in the UK (Tropical Fish magazine). This monograph includes
not only the history of discus taxonomy to the last detail, but
also a new, easy to understand taxonomy. It is a result of my
over 300 Amazon field trips and research work during the last 50
years. I am sure it will be the reference book for Discus for
today's generations and for those to come. It should be of
great interest to your website-information. Please do not
hesitate to contact me for any question you may have. Below I
also copy in a few of the websites talking about my new book.
And, I wanted to tell you: volume 2, which I am hoping to finish
end of this year, will have everything about tank breed varieties
including interview with 300plus breeders from 4 continents.

Discus Stocking - 05/07/2006 <<Hi, Karen. Tom with
you.>> I have a 47G column. It is planted, and doing well. I want
to put a few 2.5 inch Discus in it. How many may I safely put
in? The dimensions are 31" tall, 20" wide and
18" deep front to back. There are no other fish, save 1
Otocinclus. I would do a small school of cardinal tetra, but
I know I am restricted due to the lack of surface area. <<Karen,
I wouldn't go with more than three of these fish since they
won't remain this size. You're already aware of the restricted
surface area with this style of aquarium and are almost certainly aware
of the need Discus have for exceptional water conditions. They're
going to need frequent water changes and strict attention to vacuuming
the substrate in your tank. These are wonderful fish but it seems like
any parasite within a city block of these guys will find them.>>
Thanks for the expert opinion, for free, YAY! <<Well, I can't
vouch for the "expert-ness" of my opinion but, it is
absolutely free! :)>> Karen <<Best of luck. Tom>>
Discus Book Recommendation - 04/27/06
I will order it, and thank you very much for the time you and
everyone involved at WWM so generously give. I raise my
net to you in a salute! I shall make a donation in your
honor! Would you possibly have a recommendation for a book on Discus,
other than Mr. Wattley's? Would you order
his? Is that a fair question? Yours truly, Karen < I love
this question! Recently I went out and bought all the new and old
discus books I could find. I am kind of an aquarium history buff too so
I was not too far from my element. An excellent to the point book about
discus is the "Back To Nature Guide to Discus " by Dick Au.
Unfortunately it is out of print and Dick has all the remaining copies.
Jack Wattley's book "Discus For The Perfectionist" has
lots of good information. It is a series of questions and responses
from famous discus aquarists from all over the world. It is interesting
to note that Jack does not respond to any of the questions. For the
money the best book is called "Exotic Discus of the World".
It is a composition written by numerous authors about the very fine
details and tricks on getting ,breeding and raising
discus. It can be obtained through Oliver Lucanus at his
website at Belowwater.com. I use it often as a reference to WWM
questions on discus.-Chuck>
Discus book, NNS (Non-Native
Speaker) ? 3/3/06 dear bob just a quick line to say
thank you for all the work you do for us fish keepers am new to this
game i.e. discus keeping Am i right in thinking that you have done a
book on the subject ? if so where can i get a copy from thanking you a
gain des <Mmm, no freshwater books in print. Bits and pieces
archived on WWM, including re Discus. Bob Fenner>
Discus Question 2/10/06 Good Afternoon,
<Morning here/now> I am starting up a 65 gallon planted discus
tank and was wondering if I can have other fish in with them
(specifically angels, an elephant nose, cardinal tetras and maybe dwarf
gouramis). <The cardinals would be fine (if large enough, the discus
small enough), the other fish species are not recommended for various
reasons> Also, could you please tell me how many fish I
can house in a 65 gallon aquarium. <Could start with five discus of
smallish size (less than three inches in diameter), likely having to
remove all but two, three in time> Another question is with regards
to sand/gravel. I have been reading up on silica sand, black
beauty and other sandblasting sand. Could you please tell me
which is the best to use in my tank (currently running bare bottomed).
<Mmm, none of these would I choose. Look to Fluorite, lateritic
material... for function...> What medication (if any) should I
always have on hand. Thanking you in advance for any advise
you can offer. Lori <None. Like military hardware, lack of
knowledge/intelligence re same, you're too likely to use it. Bob
Fenner>
Starting With Discus 12/10/05 Yes, fist of all
I just want to say thanks for all of your hard work on putting this
page together. It has been a great source of reference for many
years. Ok, on with the question. I just bought a 75 gallon tank
with the hopes of raising discus, but I don't know if I have the
right set up. I am using a stealth heater two Filstar Rena canister
filters xp2 and xp3. I am using medium and small gravel somewhere
around 110 pounds in all. And a few fake plants and driftwood. Is this
ok please let me know. Current fish in tank, 2 baby green Severums, 2
Bala Sharks, 2 catfish Pictus and 1 Black Ghost knife 10 in. < There
are two kinds of discus, wild and tank raised. Wild discus require
clean, warm, soft, acidic water. Tank raised fish are much less
demanding. Overall you need to keep the pH around 7, and the nitrates
as low as possible. Give them good food and they like to be crowded. In
the wild they are found in big schools so get a group to make them feel
more comfortable.-Chuck>
Discus Hey, I have several discus and one of them is showing
a sort of pimple along the lateral line right before the tail. The fish
seems to be eating fine and swims along without a problem but the
pimple is there with a white top on it. Should I move the fish to a
temp tank? What would you recommend for treatment? DK < I
would do a 30% water change, clean the filter and vacuum the gravel.
Watch the pimple carefully because it may be the first signs of hole in
the head disease. If it gets worse I would isolate the fish and treat
with Metronidazole. The key with discus is clean water with lots of
water changes.-Chuck>
Fish poisoned with algicide/clarifying agent Hi there. I used
a product called Accu-clear in my tank, which was going green with an
algae bloom. It had 2 of my breeding discus in it. Both discus
instantly got sick and one to the point where it was lying on the
bottom of the tank and gasping for air. Can you help me and give me
some information on what I can do to help this fish? <Change the
water IMMEDIATELY... as much as you have good water (about the same
chemistry, temperature) on hand. Increase aeration... Bob
Fenner>
Peaceful Top Dwellers Hi, <Hello Greg> I've kept
fish for most of my adult life, but never had a small aquarium until I
moved to an apartment. I now have just a 10 gallon tank. I will be
moving back into a house I'm building by fall and will go back to a
large tank. The tank has 3 high-fin rams 3 small discus one Pleco
and one cat. The rams stay at the bottom and the discus in the middle.
Are there any small (or at least slow growing) fish that are compatible
and would inhabit the top third of the tank? I figure I've got room
for two or possibly three more fish if they're not too large.
Thanks, Greg Plate <Well that is a lot for a ten gallon, as the
discus demand very high water quality to stay healthy. I would not add
anything else to this tank and am sure that by the fall you may be
severely overcrowded size wise, if you are not already. I would keep a
very close eye on the water quality and do rigorous water changes
weekly to help, but the waste produced will overload the tank soon, if
it hasn't already. Justin (Jager)><<You need a larger
tank, hyaku! RMF>>
