Etymology

Cyclocheilichthys: from the Ancient Greek κύκλος (kýklos), meaning 'circle', χείλος (cheílos), meaning 'lip', and ἰχθύς (ikhthús), meaning 'fish', possibly in …

Distribution

This species is currently understood to have a considerable natural range extending eastwards from Myanmar via Thailand, Laos, Cambodia as far as Vietnam and t…

Habitat

Little information is available but according to reports it predominantly inhabits deeper waters and can only be found in shallower zones for a few weeks each …

Aquarium size

An aquarium with base measurements of at least 120 ∗ 45 cm will be required for long-term care.

Maintenance

Prefers a dimly-lit environment and a soft, sandy substrate is recommended to allow natural feeding behaviour (see 'Diet'). The addition of some good-sized pie…

Prefers a dimly-lit environment and a soft, sandy substrate is recommended to allow natural feeding behaviour (see 'Diet'). The addition of some good-sized pieces of driftwood will provide shady patches that will be appreciated. If you can't find driftwood of the desired shape common beech or oak is safe to use if thoroughly dried and stripped of bark.

While many aquatic plants will fail to thrive in such conditions species such as Microsorum, Taxiphyllum or perhaps some potted Cryptocorynes spp. should survive. A few patches of floating vegetation would also help to further diffuse the light entering the tank and provide a more natural feel.

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

Apparently a micropredator grazing the substrate and other surfaces for small items including insects, crustaceans and worms. For it to develop the best condit…

Behaviour and compatibility

This species is very peaceful indeed but tankmates must be chosen with care as it has a somewhat retiring nature and may be intimidated or outcompeted for food…

Sexual dimorphism

Sexually mature females are likely to be rounder in the belly than males.

Reproduction

Not thought to have been bred in aquaria to date.

Notes

C. heteronema is easily distinguished from its congeners as it possesses unique, fimbriated barbels which are extended downwards when the fish is browsing for …
