| Chromis
I had 4 chromis in a 10 gallon QT tank with a blue dartfish. I'm pretty sure the chromis have been killing each other off, but I just wanted to make sure the dartfish isn't the one doing it. The dartfish is about 5" long. The chromis have been dying one at a time, usually at night. They all have their gill plate ripped off and the last one had it's gills completely eaten. Since it was just the gills being injured, the other chromis are the culprit right? There's only one left now. |
