Red Devil
Amphilophus labiatus
A notoriously aggressive cichlid that somehow also becomes your best friend.

About
The red devil (Amphilophus labiatus) is one of those fish that demands respect long before you add it to your tank. Native to Lakes Nicaragua and Managua in Central America, it lives almost exclusively in lake environments rather than rivers, where it hunts small fish, snails, insect larvae, and worms along the bottom. In the aquarium it earns its common name honestly. This is among the most combative cichlids available to hobbyists, and tankmate selection requires serious thought. Most specimens will not tolerate companions at all, and keeping two males together is essentially off the table regardless of how much space you offer. That said, the red devil has a devoted following among cichlid enthusiasts, and for good reason. Captive fish quickly learn to recognise the person who feeds them and will interact with activity outside the glass in a way that few other freshwater species match. They can be available in a wide range of colour forms including orange, red, yellow, white, and piebald, though wild fish are typically a more subdued grey. One identification note worth knowing: this species is frequently confused with the closely related midas cichlid, and decades of hybridisation in the hobby mean genuinely pure specimens of either are increasingly hard to come by. Breeding is achievable but requires patience and careful pairing, as males can turn on females even during spawning.
