I had 2 parrots in a 30 and one was always bullying the other one. I decided it was a territorial issue and upgraded to a 55 gallon tank and decided to put the bully in last. They said to let the fish establish then put him in so I let them in their about 5 days prior to adding the bully and now the same issue is there accept its the other way around and worse. Before when the bully was in the 30 with the other parrot he would chase him to a corner. Now the guy that was being bullied is flaring his gills a lot and is chasing/following him everywhere. This morning I didn't see him doing it because the other guy was hiding. Whatever shall I do? (Sorry wanted to say that because it seems funny) I want to stay away from rehoming them because the LFS only had sick looking fish and I don't want them to get sick.
