Dario tigris is a small and attractive species of ray-finned fish in the family Badidae. A relative of the better-known scarlet badis (D. dario), it is found in shallow, slow-moving waters of northern Myanmar. It was originally believed to be a colour form of D. hysginon,[1] but in 2022 it gained species status.[2] It may be found in the aquarium trade.
D. tigris is probably endemic to northern Myanmar and possibly to the state of Kachin, close to the city of Myitkyina. A pair of males from separate localities were included in the type series of D. hysginon with details given as "stream about 1.5 km on road Myitzon-Myitkyina" and "ditch marginal to fish ponds about 40 km north of Myitkyina, on road to Myitzon".[1]
Habitat
No details are available regarding its habitat, but the possibly sympatric D. hysginon shows a marked preference for small, often murky pools with dense growths of aquatic plants or submerged grasses.[3]
Diet
Dario species are micropredators feeding on small aquatic crustaceans, worms, insect larvae and other zooplankton. In the aquarium hobby, it is advised to feed them a varied diet of Artemia nauplii, Daphnia, grindal, microworms, and banana worm.[3]
