I have 4 corys in my tank, water is fine, but they are nuts in there. There is a large one behind a plant that keeps going up and down the glass, and another one that is on the other side of the plant. If any of the other corys come to that corner, it chases them away from there. Any idea what is going on? Could it be breeding time in there? They were all friends the other day, but now they have devided my tank. Any ideas?
