About

Boraras urophthalmoides is a tiny cyprinid of peat swamps and bogs in Southeast Asia. FishBase identifies it by a darkened first dorsal-fin ray, dark spots at the caudal and anal fin bases and a prominent lateral stripe that fades on the peduncle, and records a maximum of 4cm TL. Seriously Fish, by contrast, gives 1.6cm SL, and fish in the trade rarely exceed about 2cm. That site suggests 20-28C, pH 6.0-7.0, 1-10 dGH and a 45 x 30cm base. The lateral stripe together with the round spot at the tail base reads like an exclamation mark, which is the origin of the English name. Extremely peaceful but small and timid, it suits a species tank or equally small companions. It is a continuous spawner with no parental care. The IUCN rates it Near Threatened and it is not covered by CITES.
