Somphongsi Rasbora

The somphongsi rasbora belongs to the same genus as the harlequin and lambchop rasboras, but is much less well known. Its body is pink-silver or salmon-toned; the typical black triangle of the genus has turned into a thin horizontal band running from the middle of the body to the caudal peduncle. It is a rare species whose natural habitat has shrunk greatly; fish bred by enthusiasts should be preferred over wild-caught ones.

• At least 40 liters for a group of 8–12, with a calm, heavily planted layout.
• 23–26°C, soft water between slightly acidic and neutral.
• Broad-leaved plants such as Cryptocoryne and Anubias, floating plants and dim light.
• Gentle flow; regular, small water changes (20–25% weekly).

Omnivorous. It accepts fine flakes and micro granules; frozen cyclops, daphnia and newly hatched brine shrimp help maintain its color and condition.

Calm, peaceful and somewhat timid. It swims as a group in the middle layer, close to the plants; in a well-stocked, quiet aquarium it comes out into the open. Like the other members of the genus, it lays its eggs on the underside of broad leaves.

Good companions: other small rasboras, Boraras species, small tetras, otocinclus, dwarf corydoras species, shrimp.

Avoid: active and large species, any fish with a mouth big enough to swallow it, fin nippers.
