Thanks but I don't have anymore hiding places I can add to the tank...if I did though I would for sure add them. I have about 50 pounds or so of natural rock if not more and also lots of plants as well as a couple big pieces of driftwood. All he does though is go around the "barriers" I create. As far as the temperature, its always at a steady 76 degrees. Also, I said that it was a green texas and that was my bad; I dunno why I said that. I meant to say they're regular texas cichlids. & I believe I've found out the problem as to why hes so aggressive all of a sudden. His color is darker in the back half of his body and lighter in the front half of his body. He was all light colored on his body before this aggression, so I looked it up and tried to find out why his colors had changed. Come to find out, he is in "breeding mode". This explains why hes always swimming with my bigger parrot cichlid and "vibrating/shaking" when hes near the bigger parrot cichlid.
