Care at a glance

The lambchop rasbora looks much like the familiar harlequin rasbora, but is slimmer and coppery orange, with a narrow black marking shaped like a small hook. In a school this gives a warm, orange whole that stands out beautifully against green plants.

It is peaceful, small and easy, with a preference for soft, slightly acidic water and some leaf litter on the bottom. Keep it in a decent group and with equally calm tankmates; you will then see it swim in tight formation.
