Not sure whats wrong but it looks a little limp, kind of crooked, not swimming to the top often, just hanging out near the bottom to middle, only ate very little for last 2 days. Just does not look right
? My params are 0 nitrites, 0 ammonia and 10 nitrates, did partial water change as usual on sat. My friend fed the fish last week while I was on vacation and I suspect she may have overfed a little. Everyone else in the tank looks great (cories, guppies, danios and ghost shrimp) Any suggestions...................
