Hey guys my discus started acting strange. They have stopped swimming as much as they normally do. They are grouping up in the corners of the tank and some of them lay in between rocks for a while. They have eaten a few flakes since this has started. I have 1 clown loach (2.5in) 2 plecos 2 cory cats that all seem to be doing fine. Mo signs of ich or anything like that. I did have 2 pearlscale gold fish in their but i found out that that wasnt a good idea and i took them out. I also did a 30% water change.
Whats going on??
