i have heard that convicts are pretty mean but today my friend gave me a red zebra cause he got rid of his tank and i put him in my convict tank. (75 gallon). within a few hours of putting the zebra in the established convict tank, he beat up my breeding pair of cons. I know i should not mix africans with cons but i had no choice. the zebra would have been flushed other wise. I am dumb founded. (zebra is now at Petco). Anybody else find convicts to be push overs? im pretty mad about the situation.! poor cons...
