Described from 'Peria Creek, Kwagira River, eastern Papua New Guinea' and despite its popularity in the aquarium hobby is endemic to a relatively small area in the country's Northern and Milne Bay provinces.

It's been recorded in the Musa and Kwagila river basins which drain into Dyke Ackland Bay and Collingwood Bay, respectively, and presumably occurs in drainages between the two as well.

Wild specimens are not available in the aquarium trade with all those in the hobby bred on a commercial basis and apparently originating from a single collection in 1981.

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.

Anything worth adding

Describe what you saw, or which part of the source says this.

Habitat

Primarily inhabits low altitude, heavily-vegetated forest streams with slow to moderate current and clear water. Air temperatures in Papua New Guinea are quite…

Aquarium size

An aquarium with base dimensions of 60 ∗ 30 cm should be the smallest considered.

Maintenance

Best kept in a densely-planted tank and an excellent choice for the carefully-aquascaped set-up. The addition of some floating plants and driftwood roots or br…

Water conditions

Temperature: The air and water temperatures in its natural habitats do not vary a great deal and in aquaria the fish tend to fare poorly unless maintained with…

Diet

Feeds chiefly on floating or suspended zooplankton, phytoplankton, and invertebrates in nature, and in the aquarium must be offered items of a suitable size. I…

Behaviour and compatibility

Peaceful and suitable for well-chosen community aquaria alongside fishes of comparable size, disposition, and requirements with many cyprinids, gobiids, eleotr…

Sexual dimorphism

Males are more highly-patterned and colourful than females and the unpaired fins become noticeably extended as they mature.

Reproduction

This species is an egg-scatterer exhibiting no parental care and will consume its own eggs and fry given the opportunity. Since all aquarium fish appear to der…

Notes

This species is also traded as 'forktail rainbowfish' or 'yellow forktail', and it's also undergone several changes in scientific name since description. Pseud…
