They are not wimps my 14 incher tried to kill a 6 inch pearsei cichlid! He/she would have suck seeded if i did not remove the pearsei cichlid! He shows my Asian upside down catfish who is boss but i am putting the Asian upsidown catfish in a other tank and sometimes attacks his 12 inch pleco buddy! mabey some are wimps but some are plain mean????
