Lambchop Rasbora Care Guide

The Lambchop Rasbora is a petite and elegant schooling fish with a translucent golden-orange body and a bold black marking along its sides. The marking is narrower and more angular than the characteristic patch of the closely related Harlequin Rasbora, giving this species its memorable common name. Mature individuals may develop especially rich copper, orange and red tones, with males often showing the strongest colour.This species is peaceful, active and most confident when moving among several companions. A group creates a lively display as the fish weave through vegetation and pause together in the middle areas of the aquarium, while males may briefly display to one another without causing serious aggression. Their small size and gentle nature make them a popular choice for carefully selected community aquariums.Lambchop Rasboras originate in mainland Southeast Asia, including parts of Thailand and Cambodia, where they inhabit slow-moving streams, forest pools and peat-influenced waters. These habitats are often shaded by dense vegetation and surrounded by leaf litter, submerged roots and other cover, producing relatively soft, acidic water stained by natural tannins.Trigonostigma espei was formerly placed in the genus Rasbora and is closely related to the Harlequin Rasbora and Hengel's Rasbora. Although it is sometimes confused with those species in the trade, its smaller size, warmer body colour and distinctive lamb-chop-shaped lateral marking help distinguish it.
