I purchased 2 Apistogramma sp. (male-female pair) and added them to my 30gal planted. They get along fine with the other fish. (Panda cory, cardinals,bumblebee gobies, hatchets, keyhole and rams) But the male is really stressing out the female. She is paler and always hides and comes out during feeding but the male chases her all the time other then feeding. I was wondering if the aggression will go down or will this continue. It is heavy planted and gives them plenty of spots to hide. Anything I can do, other then removing one of them??
