"This can become a pretty nasty character in your fish tanks and if housed with other fish can be lethal. Cichlids such as the Pikes from the Crenichla genus that can look after themselves would be the best bet for other tankmates. I have housed them with Synodontis and they can make a lot of damage to their fins and can kill smaller specimens by charging them midriff and causing internal injuries."
Not my words. Just info I'm finding.
