We'll use this thread to discuss anything and everything that has to do with bait tanks. Ok I will start. I started a bait tank about 2 weeks ago. I've been keeping bluegills and sunfish. The fish have been doing pretty well and I've only had a few die mostly likely from being hooked to deep. Its a 55 gal tank and I change about 20 gallons a week. Well 2 days ago I caught about 12 sunfish out of a creek and brought them home and threw them into my tank. The fish were doing pretty good and a few died most likely from stress. Well today I went into my garage and found all of my fish had died except a few gills. The fish lost all of their color and were very badly bloated. What did I do wrong?
