You think yours is a sissy? I have two oscars that are breeding and yet seem to have made pets of two goldfish that I gave them as a treat back in October! These goldfish have been there so long they wised up and now huddle with my blood parrots.
yes... it is true, contracdicting the notion that oscars are aggressive. in my case, i have an angel fish that grows 5 inches body wide now, while the oscars are 15 inches long.
The parrots have tired to eat the goldfish but their mouths are too small.

parrots are known to be fin nipper. although they have small mouth, they used to attacked and nipped the fins and scale of their tank mates.
