Batasio Feruminatus

Datasheet

General Description

Batasio Feruminatus can be distinguished from other species in the genus by its unique combination of characteristics, including an adipose-fin base in contact with the base of the last dorsal fin ray, an oblique dark bar in front of the dorsal fin, a thin black midlateral stripe, and a relatively long adipose-fin base. It has a laterally compressed body shape, large sensory pores on the head, a narrow mental region, and distinctive processes on the vomer. The species is known for its transversely elongated, bar-like entopterygoid.

Aquarium Setup

To provide proper care for Batasio Feruminatus, a tank setup resembling a flowing river environment is recommended. This includes a substrate of variably-sized rocks, gravel, and large water-worn boulders. Driftwood branches, roots, and robust aquatic plants such as Microsorum, Bolbitis, or Anubias species can be added, attached to the décor. Clean water conditions, with spotless water at all times, are crucial for the well-being of this species. Adequate levels of dissolved oxygen and water movement should be maintained using canister filters, powerheads, etc. Weekly water changes of 30-50% are advisable.

Behaviour

Batasio Feruminatus is not competitive and should not be housed with significantly larger or more aggressive fish. Peaceful schooling cyprinids are ideal tank mates, along with akysid or sisorid catfish from recommended genera such as Erithistes, Erethistoides, Hara, and Pseudolaguvia. Balitorid loaches from suitable genera and selected members from Cobitidae and Nemacheilidae families can also be compatible. Careful research is essential to avoid excessively aggressive or territorial species.

Feeding and Diet

In their natural habitat, Batasio Feruminatus likely feeds on small aquatic crustaceans, worms, insect larvae, and zooplankton. In captivity, their diet should consist mainly of small live or frozen chironomid larvae (bloodworm), Tubifex, Artemia, and mosquito larvae. Prepared sinking foods may also be accepted, although newly-imported specimens may initially refuse them.

Reproduction & Dimorphism

Successful breeding of Batasio Feruminatus has been achieved with other members of the genus. Spawning can be induced by significant water changes with cool water when the fish show signs of spawning condition. The eggs are scattered randomly and typically hatch within two days. Sexual dimorphism in this species is unknown, although males in related species may possess a distinct elongated genital papilla anterior to the anal fin.

Habitat and Distribution

This species is an obligate dweller of headwater streams and upper sections of smaller rivers with fast-flowing, oxygen-rich water, and sandy/rocky substrates. Batasio Feruminatus is primarily found in the Ataran River system in southern Myanmar, specifically in the Chon Son stream between Phadaw and Kyondaw. The Ataran River, a tributary of the Salween drainage, extends into Thailand as the Kasat River. The habitat of Batasio Feruminatus includes clear, forest-shaded waters with submerged driftwood and leaf litter, sharing its environment with various other fish species.
