Devario acrostomus Care Guide

Devario acrostomus is a freshwater danionin from the Mekong basin in Laos, an active mid-water schooling cyprinid.

Overview

Devario acrostomus is a freshwater cyprinid described by Fang and Kottelat in 1999. According to FishBase and Wikipedia, it is currently known only from the Mekong basin in Laos. It is a small to mid-sized danionin distinguished by a sharply upward-directed, pointed mouth and relatively long rostral barbels.

Taxonomy

  • Family: Cyprinidae
  • Genus: Devario
  • Scientific name: Devario acrostomus
  • Described by: Fang & Kottelat, 1999
  • Former name: Danio acrostomus

Habitat

FishBase records the species from the Mekong basin in Laos, where it occupies forest stream pools with clear water. Reported conditions range from standing to relatively swift-flowing waters. It is classified as a benthopelagic freshwater fish of tropical climate.

Tank requirements

  • Minimum tank volume: 80 L (about 21 gal)
  • Temperature: 20-26 °C (68-79 °F)
  • pH: 6.5-7.5
  • GH: 5-15 °dGH
  • School size: 6 or more individuals
  • Lifespan: 3-5 years

Diet

FishBase assigns the species a trophic level of about 3.0, indicating a position consistent with small omnivorous feeders. In the aquarium an omnivorous diet of prepared and small live or frozen foods is appropriate, offered around twice daily.

Compatibility

This is a peaceful, diurnal schooling species that occupies the middle water column. It is best kept in a group with comparably active, non-aggressive tankmates and should be housed away from slow or timid fish that cannot match its activity.

Conservation status

IUCN Red List: Data Deficient (assessed 2011), meaning available information is insufficient to evaluate its extinction risk.
