There are many biotopes in Central America and cichlids are found in most of them.
Red Devils are from Lake Nicaragua and Lake Managua. They are found over and around large rocks in this habitat.
Trimacs are found in rivers in Northern Central America (Mexico, El Salvador, ect). Many rivers in this region have large pieces of driftwood in them, but still have a decent amount of rocks too.
Almost all habitats is Central America have hard water. Keep this in mind when setting up your tanks.
