Hyalobagrus is a genus of bagrid catfishes found in Southeast Asia.
Species
There are currently three recognized species in this genus:[1]
- Hyalobagrus flavus H. H. Ng & Kottelat, 1998 (Shadow catfish)
- Hyalobagrus leiacanthus H. H. Ng & Kottelat, 1998
- Hyalobagrus ornatus (Duncker, 1904)
Distribution
Hyalobagrus species are distributed in Asia.
Description
These catfish species are small and transparent.[2] The three species can be distinguished by differences in body shape, coloration, and the degree of serrations on the anterior edge of the pectoral fin spine.[3] The three species range from about 3–4.4 centimetres (1.2–1.7 in) SL.[4][5][6]
Hyalobagrus species are sexually dimorphic, males possess a genital papilla, and gravid females are easy to spot since their blue-green eggs are visible through their bellies.[2]
Ecology
These catfish are mid-water swimmers.[2] They are also schooling fish.[3] In their natural habitat, they are almost always found closely associated with submerged vegetation.[3]
In the aquarium
H. flavus and H. ornatus are known to be exported for the aquarium trade.[3][6] H. flavus first appeared in the hobby in the 1980s.[3] They seem to do best in a heavily planted tank with tankmates that will not out compete them for food.[2] They are a peaceful, diurnal community species that accept all kinds of foods.[3] None of these species have been bred in captivity.[2]
