Maybe a 15cm pleco. The Oscar will get large enough to eat either a convict or a firemouth, and as soon as it's big enough it will eat them.

The Cichlids was created in 1979.
The firemouth is a fish. It is a cichlid, native originally to South America and now also often to the freshwater aquarium. They are neither a terribly large nor small aquarium fish and, as is often but not always the case with animal species, the males are larger. They grow to a length of approximately six inches (15cm).
It is possible if the tank is sufficient in size and provides enough territories and enclosures.
Firemouth cichlid (Cichlasoma meeki) are fairly large fish growing out to about 6 inches. A reasonable sized tank for a pair of firemouths (and nothing else) would be 36 inch x 18 inch x 18inch. If you wish to keep other fish with them they will have to be fairly large fish. Select from the other mid sized cichlids from South America. You can not keep African cichlids with South American ones successfully. To house these types of largish fish you will probably need to have at least a 6 foot tank or larger.
Yes they can. There are several observable differences when the Firemouth (Cichlasoma meeki) are fully grown. The male has a much brighter red than the female. He is usually a bit larger and both his ventral and dorsal fins are more flowing and pointed.
