Azul Peacock Bass (Cichla piquiti) are native to the rivers and tributaries of northern South America in Colombia, Venezuela, Guianas & Brazil. They have also been introduced to areas outside of their native habitat including: Florida, Hawaii, Puerto Rico and Singapore. Key characteristics to look for to positively ID Cichla piquiti include: grayish brown body color, bluish coloration on fins, vertical dark bars throughout the length of the body and yellow dots along with a eye-spot on their tail fin. Cichla piquiti are very fast growers, who will grow quickly to about 16 to 18 inches in length and then over time depending on food source, water condition and tank size, reach an eventual adult length of upwards of 29 inches. They are a very fast swimming and boisterous species that will hit prey items (even pellet foods) with amazing force that can startle other tank mates and their human owners alike.
Despite the aggression they show towards their prey, they are not considered to be that aggressive towards other suitably sized tank mates. The reason size is so critical is that tank mates that are not at least half as large as the Azul Peacock Bass will usually be reguarded as prey. So despite not being too aggressive towards tank mates, their shear size and fast, burst ambush style feeding behavior make Azul Peacocks a poor choice to keep with timid fish species, who may find aquarium life with an Azul difficult.
