Etymology

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

Distribution

Endemic to the island of Borneo where it's known from the Indonesian provinces of Kalimantan Barat (West Kalimantan) and Kalimantan Tengah (Central Kalimantan)…

Habitat

Inhabits black water streams and rivers associated with ancient forest peat swamps. The water is typically stained brown due to the release of tannins and othe…

Aquarium size

An aquariumwith base measurements of 180 ∗ 45 cm or more is required for long-term care.

Maintenance

Choice of décor is not as critical as water quality and the amount of open swimming-space provided. We suggest keeping it in a large, well-furnished aquarium o…

Diet

According to stomach analyses of wild specimens it feeds mainly on invertebrates both aquatic and terrestrial, particularly insects. In the aquarium it's easil…

An ideal resident of the larger, well-furnished community set-up though it might upset slow-moving or timid companions simply by its size.

There are plenty of suitable tankmates including many cyprinids, loaches, cichlids, catfish and characins, but as always when selecting a compatible community of fish proper research is essential. A community based around one of its native countries or river basins would also make a worthwhile project with some interesting alternatives (see 'Habitat' for some examples).

It is a gregarious species by nature and ideally should be kept in a group of at least six. The fish show better colours in the presence of conspecifics, are less nervous and the display on the whole will appear more natural-looking.

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.

Sexual dimorphism

Sexually mature females are likely to be thicker-bodied and perhaps a little less colourful than males.

Reproduction

Not thought to have been bred in aquaria to date.

Notes

As with others in the genus little has been written regarding the captive care of this species but it makes a peaceful and unusual addition to larger aquaria. …
