I have 1/2 inch blue zebra babies in my 110 gal.tank of assorted africans. I was feeding the fish, and couldn't believe what I saw. Two of the baby zebras were flaring and displaying aggresion at each other! I just started laughing.:grinyes: I shouldn't be surprised though. The male that fathered the fish is super nasty and aggresive. :devil:He chases anything and everything around the tank. A lot of the time, he chases the other fish and backs them into the corners. Hard to believe that something as small as 1/2 inch can be so territorial.
