Etymology

Rhinogobius: from the Greek rhinos, meaning 'nose', and the generic name Gobius. chiengmaiensis: named for Chiang Mai (also written Chiengmai) province in nort…

Distribution

Known only from the middle-and-upper Chao Phraya river system in central Thailand including its major tributaries the Ping and Nan rivers. Type locality is 'Ch…

Habitat

Inhabits smaller rivers, tributaries and streams with substrates of gravel, rocks, boulders, and exposed bedrock which undergo seasonal variations in water flo…

Aquarium size

An aquarium with base dimensions of 60 ∗ 30 cm is large enough to house a small group.

Maintenance

Not difficult to maintain under the correct conditions; we strongly recommend keeping it in a tank designed to simulate a flowing stream with a substrate of va…

Water conditions

Temperature: 18 – 26 °C. It can temporarily withstand warmer conditions provided dissolved oxygen levels are maintained. pH: 6.0 – 8.0 Hardness: 2 – 15 dGH

Diet

Rhinogobius spp. tend to be opportunistic carnivores feeding on a range of small invertebrates, crustaceans and similar in nature. In the aquarium they should …

Can be kept in a community provided tankmates are chosen with care.

Peaceful, pelagic species which inhabit similar environments in nature such as Tanichthys or Danio species are perhaps the best choices for the upper levels, but we've also seen Rhinogobius spp. being maintained alongside barbs, small characins, poeciliid livebearers, etc.

It should not mixed with other Rhinogobius spp. since it's not yet clear if they're capable of hybridisation, but other stream-dwelling gobies from genera such as Stiphodon, Sicyopterus, Sicyopus or Schismatogobius spp. generally make good companions.

Less suitable are freshwater shrimp from genera such as Caridina and Neocaridina as these are likely to be predated upon.

Other bottom-dwellers can include diminutive loaches from genera such as Gastromyzon, Pseudogastromyzon, or Acanthopsoides, and in high-turnover set-ups obligate torrent-dwellers like Annamia, Homaloptera, etc. Avoid those that feed aggressively or are excessively territorial, e.g., many Schistura spp.

Larger fishes are best omitted although in very large set-ups it may be possible to add a few non-predatory, surface-dwelling ones.

The majority of cichlids and other territorial fishes inhabiting the lower reaches should be avoided entirely.

While males are territorial with one another to an extent serious damage is unlikely provided the tank contains sufficient cover, and in fact they appear to actively require the presence of conspecifics.

Aim to purchase at least two males and as many or more females or the fish may become listless and inactive.

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

Adult males are more intensely-coloured and develop slightly more-extended dorsal and anal fins than females.

Reproduction

In nature reproduction occurs from May to August in summer and December to March in winter, though in aquaria it can be bred year-round and is among the less-p…

Notes

This species has been exported for the ornamental trade but often labelled as the congener R. mekongianus. Although the two do appear relatively similar R. chi…
