Etymology

Pethia: the generic vernacular name for small cyprinids in the Sinhala language.

Distribution

Type locality is 'Barapani Lake, about 20 kilometers north of Shillong, Khasi Hills, Meghalaya, India, elevation 1100 meters', and appears to be endemic to Meg…

Habitat

A benthopelagic fish mostly recorded from streams and minor tributaries at relatively high altitudes of more than 1200 metres AMSL with cool, clear, well-oxyge…

Aquarium size

Base dimensions of at least 75 ∗ 30 cm or equivalent are required.

Maintenance

Displays its best colouration under dim lighting and should look particularly effective in a heavily-planted arrangement with a darkish substrate, or a set-up …

Displays its best colouration under dim lighting and should look particularly effective in a heavily-planted arrangement with a darkish substrate, or a set-up designed to resemble a flowing river or stream with a substrate of variably-sized rocks and gravel and some large water-worn boulders.

This could be further furnished with driftwood branches and plants such as Microsorum, Bolbitis, or Anubias spp. which can be grown attached to the décor.

Since it naturally inhabits running water this species should never be added to a biologically immature set-up as it requires stable water conditions, and weekly water changes of 30-50 % aquarium volume should be considered mandatory.

Where does this come from?

My own experienceFor example, I've kept twelve in a planted 60 cm tank since March 2024.A website I sawFor example, an IUCN Red List assessment, a museum catalogue or a FishBase page.A paperFor example, Marshall et al. (2011), Water temperature differences in interfluvial palm swamp habitats of Paracheirodon axelrodi and P. simulans.A book, or something not onlineFor example, Tappin (2010), Rainbowfishes: their care and keeping in captivity.Something already on the pageFor example, the Behaviour and compatibility section already says this.

Diet

Wild fish are probably foragers feeding on diatoms, algae, organic detritus, small insects, worms, crustaceans, and other zooplankton. In the aquarium it's eas…

Behaviour and compatibility

Very peaceful but unlikely to make an good choice for the general community aquarium due to its preference for cooler temperatures. Fishes inhabiting similar b…

Sexual dimorphism

Adult males are noticeably smaller, slimmer, and more colourful than females, especially during the spawning season.

Reproduction

Unreported.

Notes

This species is not well known in the aquarium hobby and only available outside India on occasion although efforts are being made to produce it on a commercial…
