I had 3 angelfish in my 45 corner tank but one died. But it was being bullied by one of the other angelfish so I think it was killed or died of being harassed. Now I have the 2 left in the tank and I am leaving it that way. It is a tall tank so no upgrading for me, thank god, I have enough tanks. But I do want a 55 gallon for cichlids one day. When I move maybe, it will be in my mom's house she bought for me and my sis to have when she is no longer with us.
