The espei rasbora, also called the lamb chop rasbora, is a hardy cousin of the harlequin rasbora. These are a separate aquatic species and have a more distinct lamb chop shape black mark on the body than the harlequin rasbora. The fish are caught in smaller streams in Thailand. Lambchop (or lamb chop) rasbora eat flake food and prefer to school in groups of five or more. Espei are a wild caught species, so size varies based on whatever the fishermen caught that week and exported.
