You can get a mate for it and have lots of babies (more than you know what to do with), or you can probably keep it with other cichlids of similar size and temperament. My convict lives with a gold severum and a firemouth with no problems. If you want to get a school of fish to brighten up your tank, I would suggest barbs. They are hardy and quick, and too big to fit in the con's mouth. I also keep tiger barbs in that tank and they do fine.
