From reef to tilapia (and back again)
4/7/16
Crew! I just picked up a 200 gal Oceanic Reef Ready and I needed your
advice on how to get started. While I have found lots of info here on
the reef setup (I plan on converting to a C2C skimmer and Bean
overflow), my loving wife has asked me to set it up as a Tilapia (mixed
Mozambique & blue) aquaculture tank to see if she wants to try
aquaculture. I don't think she's going to like it in her living room,
but...
<Agreed... at likely stocking densities... an eyesore, and smelly too>
What would be the best way of setting up the system to minimize
transition when she changes her mind?
<Use the filtration as it is.... including the sand mentioned below...
the Tilapia/Oreochromis can stand the bit more hardness and elevated pH
it will lend>
The system as it stands has a Little Giant 4-MDQX-SC external pump, 400
lbs deceased live rock (previous owner's ex drained it with over $5k
live coral still inside: still crying), 400 lbs live-ish sand, a 40
gallon sump in the
stand, a large unlabelled protein skimmer sans pump,
<Leave the skimmer and old rock out; till you convert it to marine>
and a 72" 4x96W Orbit PC light. The equipment is older, but was working
just fine until it was shut off and drained (sigh). My ultimate goal i
think will be a medium light softies tank. I'm considering a DIY
cyclonic settling tank prefilter and salinity of 1.01ish
<? Not for the Tilapia>
with about 200 lbs each of rock and sand in-tank for bio filtration. Any
other thoughts?

Tilapia zilli/Oreochromis aureus cross?

Tilapia/Oreochromis Cross
Greetings Crew, Hope you are doing well. Do you think there is any possibility
of Tilapia zilli crossing with Oreochromis aureus? I wouldn't think it is
possible, one is a mouthbrooder and one is a substrate spawner
of two separate genus. None the less, I have been raising these species together
and am noticing offspring resembling the two. They are in outdoor aquaponic
ponds, so I have yet to noticed the actually breeding, just
offspring. If so would their offspring be sterile? Thanks for any input.

< In the small confines of a pond, it is entirely possible that sperm from one
species could fertilize the eggs of another. Both are extremely closely related
and are only technically separated by the spawning
techniques.-Chuck>
Spotted Tilapia - Redbilly. Repro. issue
4/24/12
Dear Sirs,
Good Day,
Appreciate your good efforts on the valuable web site of WWM, I've one
query hope I can find the answer at your good side:
- I've Spotted
tilapia in my 25 gallon tank, spawned and I caught the eggs (sticky eggs
to a PVC pipe) and now all fry hatched (2 days) but They are sticky to
each other trying to release themselves, please advise will they be free
or they will live sticky to each other.
<They will become free swimming within 24 hours..
- Did I make it
wrong to collect the sticky eggs after fertilized,
<Nope. Don't be too worried! Tilapia mariae breed like rabbits. So even
if you make a mistake this time, you will have thousands more eggs to
play with! Tilapia mariae are good parents. It is usually safe to leave
them with their eggs. Remove the fry after 1-2 weeks. At this size they
will be easy to catch and move. The parents will also stop looking after
them at around this age.>
Thanks your help.
Moataz
<Most welcome. Cheers, Neale.>
Coptodon bythobates, Tilapia repro.
4/16/12
Hello Crew,
Last time I messaged Neale helped me with a blind Featherfin catfish
that was in bad shape. First of all I will let you know that he is doing
awesome and is not a Featherfin as first thought but actually a Lace
Catfish.
<Ah, Synodontis nigrita. Have kept one of those. Can be REAL PUSHY at
times… very much a catfish with attitude. On the plus side, rock solid
and can hold its own with virtually anything short of an alligator.>
He fully regained his vision and fins and is now the boss of my Cichlid
tank.
<Indeed.>
I now have another question to test your fishy brains! I recently
acquired a pair of Coptodon bythobates. My problem is that I discovered
I have a Male and a Female and they are trying to spawn.
I really cant find any information on these rare fish let alone their
breeding habits.
<Now referred to as Tilapia bythobates. Matt Clark
wrote a nice summary on this unusual species for PFK, which you can read
here:
http://www.practicalfishkeeping.co.uk/content.php?sid=2328
Breeding is much like other true Tilapia species (as opposed to
Sarotherodon and Oreochromis spp.). They're egg-layers not
mouthbrooders, and very aggressive at spawning time. Nice big fry, so
not difficult to rear. We used to keep, breed Tilapia rendalli at my
university; because it's a commercially important species, you can find
lots about this species online, in the scientific press.>
What I have found says they lay their eggs on a flat surface, but mine
appears to have built a bubble nest in the upper left corner of my tank
(at least I think that is where it is at). The Male is defending it
ferociously even keeping the Female away just not as much.
<Yes.>
He will let her close but not too close. He went head to head with a 5in
Male Venustus and sent the big guy packing.
<Absolutely typical for the genus. True Tilapia species can be (and
usually are) extremely aggressive.>
He even chased off my 9 inch Pleco! I would love to know more about
these rare and spirited fish and information is lacking even at my LFS
and library. I have come a long way in my fish knowledge since the last
time I messaged, but am by far no expert. I am wondering if maybe I'm
mistaken in thinking that they are a breeding pair, but I was sure all
of the signs were there. The Female is slightly less colorful then the
Male but they are so close in coloration and size that it is hard to
tell.
<Again, very typical for the genus. The best trait is the shape of the
"spawning tubes" or genital papillae. On males these are long, narrow,
and pointed. On females they are short and stubby. Male cichlids tend to
have longer dorsal and anal fins than the females, and at breeding time
at least females normally look quite a bit chunkier.>
They are both definitely in full breeding colors. I am baffled and
disgruntled and am wondering if I just have a moody fish.
<No; quite normal.>
Any help would be appreciated. I would hate for him to be just playing
"tough guy" for nothing and get himself killed or injured.
<Definitely possible, but unlikely. If in doubt, use a tank divider, but
it's best to try and get your cichlids to form a stable pair. Adding a
target fish, like a big catfish or a fast-moving species like a Chinese
Algae Eater can be a plus, giving the pair something to bond over (i.e.,
a common enemy!) but this assumes the target fish has space to escape
too -- otherwise it can end up damaged or dead.>
If they are a breeding pair I would rather move them to a separate tank
alone where they wont risk being injured by the big guys. In summery to
this long rant, what I really require is information on this species. A
website or a book with detailed information would be really helpful. I
can't even really find specifics on their diet. I usually never buy a
fish without knowing the specifics of their care but when I bought these
they were incorrectly labeled as red bellied Cichlids.
<What are "Red-Bellied Cichlids"?>
I only found out the truth when they started to lose their spawning
colors and I thought they were sick and did some research. So any
tidbits you can throw my way would be appreciated.
Ashley

farming tilapia... At the bottom of a learning curve
6/26/08 I was asked for my opinion regarding a project to farm
raise Tilapia recently and I was hoping to get your opinion on a few
things. First, I made it clear to the interested party that maintaining
a reef aquarium is a very different beast than farm raising thousands
of tilapia in a massive tank. <In a few ways, yes> However, his
idea was to construct the tank of concrete. <Nah! Has been done
profitably, and much less expense, time, trouble in simple "Dough
Boy" pools... If new to all this, go this route. Easier to remove
later as well> The tank will be roughly 25ft X 15ft and 4ft tall.
I'm thinking 4 inches of concrete should be sufficient for this.
<? For what? Free standing construction? You intend to monolith cast
this structure? I doubt it> What liner would you recommend?
<What? Let's stop here... you need to read, not write...> Any
specific concrete? <Plastic pool for you> As for filtration,
there will be lots of food put in the tank so the filtration will need
to accommodate this. <Oh yeah... Oh heck yeah...> Will a protein
skimmer be needed, or would this be overkill for tilapia? <Heeeee!
Won't work period...> Dissolved oxygen seems to be an important
issue considering the volume of fish, would a series of overflows
cascading the water down a material to break the water into smaller
drops be sufficient or will additional equipment be required to
maintain enough oxygen? <Please see the Net, books on freshwater
aquaculture... perhaps works by Mike Sipes... Oreochromis/Tilapia
culture is well-established...> In terms of total gallons, what
should the turnover rate be for the filtration? <...> Instead of
utilizing a sump, could a portion of one end of the tank be partitioned
off for the water to overflow into ( a large 'false back'
closed loop ) and contain the filter equipment? Also, I'm thinking
the pump driving the system should be feeding an extensive PVC grid
covering the bottom of the tank spraying water into the floor to keep
detritus and other matter from settling on the bottom. Let me know any
thoughts or experience you have with a setup of this size. Is there any
other equipment needed that I'm not considering? Regarding the
tilapia, is there a specific range of water chemistry that will be
needed, ie pH, temperature, etc. Thanks for any help you can offer.
<Stop wasting y/our time... Go to a large library, look on the Net
re sellers of books, maybe (here's a plug for all who have wasted
their time reading this thus far) (Argent Chemical
http://www.argent-labs.com/) ... as they have a very nice aquatic
science and tech. selection. Bob Fenner>
Tilapia snyderae 6/6/07 Dear crew, I love
your site! I refer back to it for almost everything. I currently breed
blue and gold rams and Hemichromis lifalili. Due to the recent
acquisition of several tanks I have decided to start a new breeding
project, which is when I happened upon Tilapia snyderae. I have
searched and searched but the only thing I could find on these guys is
that they are on the IUCN Redlist. (Sorry if I missed anything, I did
try your cached search) I was wondering if you had any information on
these guys such as adult size, tank requirements, etc. Also, I plan on
using separate breeding tanks for pairs, but I also want to do a large
show tank. Would they be compatible with the Hemichromis lifalili? Any
suggestions would be appreciated. Thank you for all your time and help.
Stevie <Mmm, Am going to place this query in Chuck Rambo's
in-box, as he is our resident "all-cichlid" expert... On
fishbase.org this species max. size is given as a mere 5 cm... I
suspect it might do poorly with Hemichromis (Please check your
spellings... particularly of scientific names)... Do see the ref.:
http://fishbase.sinica.edu.tw/Summary/speciesSummary.php?ID=10678&genusname=Tilapia&speciesname=snyderae
and use the other species of this genus names given to seek further
info. of use. Bob Fenner>

Stevie <This cichlid is only from Lake Bermin in Cameroon. It gets a
little over 2" long in the wild ,but I have seen captive specimens
almost 3"long. They come in three color morphs, green, red, and a
light brownish grey. In the wild they get lots of vegetable matter like
algae and live plants. I would recommend a diet with lots of Spirulina
in it. They also will eat insects and other invertebrates. I would stay
away from "wormy" foods. They can handle a wide range of
temperatures and pH values. They are substrate spawners that can spawn
as small as 1".They form very strong pair bonds. If you wanted to
set up an West African dwarf cichlid tank, I would recommend adding
Anomalochromis thomasi, a Pelvicachromis species, a Nanochromis
species and Hemihaplochromis multicolor. All of the Hemichromis species
are pretty much bullies. I would try H. cristatus instead of the H.
liffalilli.
