Large-scaled Apistogramma

Apistogramma pleurotaenia stands out from its genus mates by virtue of its unusually large lateral scales — proportionally much bigger than in most other Apistogramma — which catch aquarium lighting to produce a distinctive metallic shimmer across the flanks. This species is native to the soft, acidic rivers of the Brazilian Amazon and reaches a slightly larger size than many of its congeners.

Males display attractive blue-green body iridescence with dark lateral banding, and develop moderately elongated dorsal fin rays in mature specimens. The species is a competent cave spawner whose females are attentive and vigorous in their brood defense.

A. pleurotaenia occupies an intermediate position in terms of care requirements — softer water helps but it is not an extreme blackwater specialist — making it suitable for hobbyists with some experience in Apistogramma keeping.
