I hope I can get a bit of help here.
I am not new to fishkeeping, keep almost 50 tanks, breeding includes some gobies and gudgeons.
I'm new to darters.
I took five orangethroat darters at a local club auction about three weeks ago (well, no one else wanted them).
The fish are juvenile, about 1", kept in a 5.5g, strong aeration (agitated surface), temp 78-80, diet live artemia and frozen bloodworms, substrate river stone, no tankmates, stable biofilter, ph=7.1, kh=3, TDS=200.
Until today, the fish was active and looked happy.
Problem: one of them is "limping", almost falling on its side when it moves now. No other visible symptoms of a disease, so nothing I can try treating for.
I realize that the chances of diagnosis based on this are slim, but perhaps this is a known problem with darters or there is something wrong I'm doing.
Thank you.
