Hello, one of my AF started to be depressed 2-3 days ago (not eating, staying mostly appart of the other AF). He doesn't seem To have any parasite nor any of my other fishes. What can I do, I lost one of my other AF this way a month ago and I don't want To loose him too. (I have 3 AF with him) they are in a com. Thank (2 glass shrimp, 3 spoted cory, one albino cory, one ancistrus, 6 rosy tetras, 4 rummy nose). Lots of live plant and covers too....
