Claro

Ancistrus claro, the gold marble bristlenose catfish (LDA 008), is a suckermouth catfish from the rios Claro and Coxipó in Mato Grosso, Brazil. It inhabits flowing streams over boulders and bedrock. Sometimes confused with unidentified fishes such as A. sp. 'L352', it has long maxillary barbels and small spots on the head, with vermiform lines on the body in males and spots all over in females. A peaceful cave-spawner, it has been bred in aquaria on numerous occasions.

Boulengerella maculata is a pelagic ctenoluciid found throughout much of the Amazon, Orinoco and Tocantins river systems. Colour pattern varies considerably, with some specimens much paler than others, and this may be correlated with water type. Random dark spots on the upper body, and a dark stripe only behind the eye when one is present, separate it from the similar B. lateristriga. It reaches 329 mm SL and needs an aquarium with base dimensions of 240 by 90 cm or more.
