Tang unable to maintain balance Bob, I recently bought two
Tangs (Naso, and a yellow eye Kole) to add to my 200g aquarium. Before
putting them in the big tank I decided to put them in a hospital tank
to give them some time to adjust to the new water without being hassled
by the other fish. <Good idea> Tonight I found the yellow eye
Kole laying on his side at the bottom of the hospital tank. Upon
further inspection the fish is still breathing. Fearing that the
problem was water quality I carefully moved the Kole tang into the sump
of the big tank where he would still be physically isolated from the
other fish but in a fully cycled tank. I also moved the Naso into the
main tank as a precaution (he looks healthy although a bit shy). I have
been keeping an eye on the Nitrates and ammonia and changing water in
the tank to keep them as low as I can while the tank adjusts to the
additional bio load. What is the probable cause for the tang to become
sick? Is possible to save him? Thanks, Rodney Korn <<In such a
large system, I discount the sudden loss of water quality as a probable
(first, primary) cause... How "recent" is recent? This is
little doubt an animal collected in Hawai'i (most Ctenochaetus
strigosus, Koles, Yellow-Eye Tangs hail from there to the U.S.)...
but I would conjecture that this animal has/had some sort of congenital
defect, or suffered some unseeable trauma through the
collection/shipping procedure from the wild... Not likely an infectious
or parasitic situation but "something" genetic, or
developmental...Bob Fenner>>
