I had a cobalt rescue in one of my tanks. And I was just able to introduce a new family of discus I bought from GLD. The cobalt was mean to everyone. When I say mean I mean nipping fins, chasing, just all around terrorizing. So I moved him to the 10gal where the new family came from. Guess what; THAT LITTLE JERK CHASES HIS REFLECTION. He is certainly not your normal discus, or is he
?
