I have just purchased my first fish after setting up and maturing my tank.
My intended tank mates were to be, 3 discus, 3 angels, 1 bristlenose ancistrus, one flying fox and a shoal of cardinal tetras. However, my first purchase was two discus and two angels. One discus was a German red/turquoise, the other a cobalt blue. Both about 2" long. When I eventually tipped the fish in, almost immediately the cobalt blue started going for the other discus. It has discovered that the German red is extremely timid and does not retaliate to the cobalt blue's attacks and so the latter continually chases the other one about, pecking it every opportunity. I took the villain back to the shop and the dealer kindly exchanged it for another of the same variety. Unfortunately the same thing has occurred! I don't feel comfortable with taking the second fish back again. As this is my first time keeping discus, although I have read much on the subject, I am at a quandary as to what to do about it. I was wondering if I need more discus in the tank? I have decided to keep just the two angels because they get on so well together and don't bother the discus, and visa versa. I think I will get two more discus, making their total 4 instead of 3.
I notice that while the attacked fish occasionally shows its colours well when being attacked, usually it goes a dark colour. This I realise is it's normal stressed colours! The attacker (the cobalt blue) usually displays vivid colours when attacking. Is this normal? I was wondering (but very dubious) if it may be a mating characteristic and that the pursuing is not all aggression. I think I hoping too much there am I not?
Can anyone assist me in solving my problem please? :(
