The Rainbow Cichlid is known as the tiniest of the Central American Cichlids. In the wild, it can grow up to just over 17cm, but when kept in an aquarium, it usually only reaches a length of about 7cm. This species is highly regarded by aquarium enthusiasts for its friendly temperament and compact size. Its signature 'rainbow' coloring is one of its most prominent and sought-after features. It's worth noting that the fish's color can vary extensively depending on factors such as its mood or breeding status.
