Relevant Information:

Aquarium Care: This is not your typical bagrid who will cruise your tank at night and have a free lunch on your tetra's on your behalf, it is a small mid-water to bottom living species that is diurnally active, constantly on the look out for foods such as small invertebrates, insect larvae etc. They area little more sensitive to water conditions than its larger relatives so weekly to two weekly water changes are a must to keep them in good condition. It is also beneficial to keep them in a shoal in a planted tank as they seem to prefer their own company. You will see them sparring with each other now and again but no damage is done. Diet: Likes all types of live food such as Daphnia and Brine shrimp. Also small frozen bloodworm and tubifex. Will sometimes take flake, but does prefer the aforementioned foods. Etymology: The genus name Hyalobagrus: hyalos, transparent, referring to translucent body, i.e., a genus of transparent bagrid catfishes. The specific name flavus: Yellow, referring to colouration in life.

IUCN Red List

Although there is no detailed information on the population status of this species, survey data indicate that it is still abundant in many parts of its known distribution. However, given that the extent of occurrence (EOO) of this species remains unknown because of the paucity of data, in addition to the fact that the habitat primarily associated with this species (blackwater peat swamp forests) has undergone large scale destruction and degradation and the uncertainty surrounding the effects of such massive habitat loss on the population, this species is assessed as Data Deficient. It will be necessary to reassess this species once more information on the distribution and the effect of habitat loss on the population is available (IUCN 2019).
