I am thinking about starting a predatory tank. I currently have a 55 gal. I have always had pretty tame fish, so I am now looking for more of an aggressive, fish eating, tank. Any suggestions???
I would like to have several fish. The same species, or different...that doesn't really concern me so long as they can house together. They don't have to to be totally aggressive, just 'munch monsters' I guess. '
african malawi haplochromis fish would make things interesting, prolly wouldn't be able to eat goldfish till they approached adult size, for the smaller species anyway. Most would happily devour guppies and ghost shrimp at any size though.
