Laubuka is a genus of small, laterally compressed minnows in family Danionidae (the danio and rasbora group), native to slow and moderate-flow rivers and streams across South and Southeast Asia - atlas records span India, Myanmar, Sri Lanka, Bangladesh, Cambodia, Laos, Thailand, and Malaysia. Atlas species run 1.5–4 in, distinctly narrow-bodied and silvery, with a sharply upturned mouth and, in several species, an enlarged, keeled pectoral fin base that lets them skitter and glide across the surface - the trait behind common names like 'flying minnow' for L. caeruleostigmata.
In the aquarium hobby, Laubuka are kept mainly by specialists as active, schooling, surface-dwelling fish - the Indian glass barb (L. laubuca) is the longest-established species in the trade, valued for its slender, near-transparent body and constant surface activity in a well-covered tank. Conservation status is mixed and concerning in places: the atlas tally includes 2 Endangered and 2 Vulnerable species alongside a large Not Evaluated share, and one species carries CARES conservation-priority status, reflecting pressure on South and Southeast Asian freshwater habitats from damming, pollution, and sand mining.
