Cichla temensis, the speckled pavon, speckled peacock bass, painted pavon, or three-barred peacock bass, is a very large South American

food and game fish. Reaching up to 1 m (3.3 ft) in length and 13 kg (29 lb) in weight, it is the largest cichlid of the Americas, and perhaps the largest extant cichlid in the world,[2] with only the African giant cichlid (Boulengerochromis microlepis) possibly reaching similar proportions.[3]

Range

Juvenile

C. temensis is native to the

native range, it is essentially restricted to blackwater rivers and their tributaries.[5]

Introduction attempts have been made outside its native range, but it has not managed to become established in Florida or Texas.[6] In contrast, it has flourished in tropical Singapore[7][unreliable source?] and Malaysia.[citation needed]

Appearance

C. temensis resembles other peacock bass species, but is generally more elongated and slender in shape.[5] Adults are highly variable in colour pattern, which has historically caused some problems, with some speculating that the variants were separate species or males/females.[8] Only in 2012 was it firmly established that dark individuals with a dense light-speckled pattern are the nonbreeders, while breeding adults are more golden-olive and lack the pale speckles, but have three broad, dark bars on their bodies and a very vibrant ventral region.[8] During the breeding season, some males also develop a bulbous forehead. Between the two extremes are several intermediate patterns.[8] No other peacock bass species is known to have such extreme variations among the adults.[8]
