Erethistes filamentosus is a tiny hill-stream catfish described by Blyth in 1860 from the Megathat Chaung system in Myanmar. The store sold it as Erethistes filamentosa.

Taxonomy & naming

Erethistes filamentosus (Blyth, 1860) is the valid name in the Catalog of Fishes, originally in another genus. The type locality is the Megathat Chaung system, Myanmar. The adjectival epithet must agree in gender with the masculine genus, so the form is filamentosus, not the 'filamentosa' used in the store listing. The epithet is Latin for 'bearing a filament'.

Morphology

Erethistes are tiny sisorid catfishes of hill streams in South and Southeast Asia, with a stiff, spiny first dorsal and pectoral fin, bony plates or tubercles on the back, and a short, rather square body.

Habitat

It is recorded from Myanmar. Further habitat data are not recorded in the sources available to the atlas.

Feeding

Diet in the wild is not recorded in the sources available to the atlas. Tiny hill-stream catfishes of this kind eat small invertebrates; in captivity they take daphnia, cyclops, baby brine shrimp and finely chopped frozen foods.

Mating

Mating behaviour is not recorded in the sources available to the atlas.

Breeding

Captive breeding is not recorded in the sources available to the atlas.

In the aquarium

It needs a mature, clean, well-oxygenated tank with gentle to moderate flow, fine substrate and small stones or leaf litter, with tiny peaceful tankmates only. Exact water parameters are not recorded in the sources available to the atlas.

Conservation

Conservation status is not assessed in the sources available to the atlas. Small hill-stream fishes are sensitive to siltation and stream alteration, but the status of this species is not recorded in the sources available to the atlas.
