Trichopsis pumila – Sparkling Gourami (Ctenops pumilus, Trichopsis pumilus var. siamensis)

It can be distinguished from congeners by its small adult size and presence of a single solid dark midlateral stripe on the body, above which is a series of dark blotches forming a second stripe. In the similar but larger, T. schalleri the upper stripe is more variable depending on the mood of the fish, sometimes fading entirely.
