I have a couple of angelfish that seemed to be chasing off all the other angels. I thought they might be pairing up so I moved the other fish to a separate tank and did a big water change with cold water (may have been too cold). The one I suspect is the male was really colored up nicely but he has been pale the last couple days. I probably messed up. The bigger fish is usually a bully and chases everyone around the tank but I noticed this one fish he wasn't bullying who was kind of staying off in a corner and coming out every now and then to chase off another fish with Attila. These two fish are fairly peaceful with each other sometimes swimming around the tank together. As mentioned, very strange for Attila. Neither have papilla and neither seem to want to start breeding. They just kind of swim around the tank. Also, I have birds on one side of the tank and the aquarium with the other angels on the other side. Should I maybe put up some black paper to give them more security? Do I even have a pair or did I act to fast? The other angels still fight a little bit and I had to take one out because it would not not stop chasing another one. These fish are not behaving like angels. Now he's started chasing the other fish. Yep. Probably not a pair. Haven't fed today though.
