Sailfin stopped eating after water change

gnikoli · 03/04/2011, 03:03 PM

A sailfin tang that has been doing well for over 6 years has suddenly stopped eating after a 20% water change (240 gal total system volume). Suspected water parameters, but they check out fine. Has always eaten mysis with vigor, but now seems unable to see it. Won't take nori when put right under its nose. No obvious injuries, but shows dark stress color most of the time, eyes are clear. 2 chromis, 1 copperband and a crocea clam are the only tank mates right now and they all look healthy and behave normally. Any ideas?

Give it another day or so, it should start feeding again. With the exception of a large, quick increase in salinity, water quality really doesn't affect fish as it does coral.

Very odd. Took a full two weeks, but finally got back to normal. No idea what happened. Tank mates never skipped a beat. Only algae eater in the tank. Maybe ate something toxic?
