The Convict Cichlid, also known as the Zebra Cichlid or Pink Convict, is a hardy fish with a pugnacious attitude. Though the males are larger, the females are the most colorful. Their spunky behavior is really interesting to behold, they will take on a fish 3 times their size. They are great in a tank with other aggressive fish, just make sure the other fish are not so big that they can swallow your Convict Cichlid whole.
These are an undemanding fish and very easy to care for. A sandy substrate with rocks, roots, and pieces of driftwood will make your Convict Cichlid feel at home. They will also enjoy plants, expecially floating plants to help subdue the light. They will re-arrange your tank however, so keep that in mind if you are going to have plants, make sure they are anchored down. They like a warm tank and can tolerant a wide range of pH, pretty much anywhere from 6.0 to 8.0, though it needs to be kept reasonably consistent.
