I have a large 4ft tank with two gouramis in it and a clarias fish. The water quality is always optimum (the water always remains crystal clear). All the fish that I bring thrive successfully in my tank but as they grow older, they start becoming very agressive. The blue gourami, for instance, always keep nibbing other fishes in my tank. It keeps on biting its tank mates untill they go away.
I am feeding my fish properly and all of them are healthy and active. The only problem is that they become aggressive after some time.
What is the reason behind that? Please help me.
