New Fish Tank Tips: Don’t place your tank next to a window. Sunlight entering your aquarium will cause major headaches in the form of green algae. Direct sunlight will also cause your tank water temperature to increase.

Peacock bass is the common name in English for several species of tropical, freshwater fish of the genus Cichla native to the Amazon River basin of South America. These tropical fish are not true basses, but are rather cichlids. They also inhabit the waters of Colombia, the Dominican Republic, Malaysia, Panama, Singapore and parts of the USA (Guam, Florida, Puerto Rico, Hawaii, and the United States Virgin Islands).
There are six known species of peacock bass. The common names for these cichlids vary somewhat depending on the region and, at times, local anglers. The list that follows matches their taxonomic, binomial names (species names) with the common names most widely used in English speaking countries:
There are many common names for these fish in Brazil (the country of their largest native region) depending on the species and stage of development. The most popular of these is tucunaré (too-coo-nah-REH). In Spanish, the generic common name for these cichlids is pav?n (pah-VON).
Although science knows of only Six species, some ichthyologists believe there may be as many as 12 in the freshwater lakes and rivers of South America.
The IUCN has never investigated the conservation status of any peacock bass species. Therefore they do not appear on the IUCN red list.
The speckled peacock bass is the largest species and can grow up to 99 centimeters (three feet, four inches) in length. The royal peacock bass is the smallest and grows to a maximum length of 55 centimeters (one foot, 10 inches). Also, most display three wide vertical stripes on their bodies and a spot on their tail fins that resembles the eyes on a peacock’s tail feathers — a feature which resulted in their English and Spanish common names. In addition, all adult males have a pronounced hump on their foreheads. Other physical traits can vary greatly depending on the species, individual and stage of development. These include but are not limited to: dark rosettes instead of stripes, light speckles, impressive shades of bright green, orange, blue and gold. The stripes, however, tend to fade in late adulthood.
