Etymology

Rhinogobius: from the Greek rhinos, meaning 'nose', and the generic name Gobius. filamentosus: from the Latin filamentosus, meaning ‘filamentous’, in reference…

Distribution

Very few details exist but the type locality is given as 'Yangso, Li Kiang, Kwangsi Province, southern China', which should correspond to an unspecified locati…

Habitat

Presumably inhabits smaller rivers, tributaries and streams with substrates of gravel, rocks, boulders, and exposed bedrock which undergo seasonal variations i…

Aquarium size

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

Maintenance

Should not prove difficult to maintain under the correct conditions; as per other Rhinogobius spp. we strongly recommend keeping it in a tank designed to simul…

Should not prove difficult to maintain under the correct conditions; as per other Rhinogobius spp. we strongly recommend keeping it in a tank designed to simulate a flowing stream with a substrate of variably-sized rocks, sand, fine gravel, and some water-worn boulders.

This can be further furnished with driftwood branches, terracotta pipes, plant pots, etc., arranged to form a network of nooks, crannies, and shaded spots, thus providing broken lines of sight.

While the majority of aquatic plants will fail to thrive in such surroundings hardy types such as Microsorum, Bolbitis, or Anubias spp. can be grown attached to the décor.

Like many fishes that naturally inhabit running water it's intolerant to accumulation of organic pollutants and requires spotless water in order to thrive, thus weekly water changes of 30-50% tank volume should also be considered routine.

Though torrent-like conditions are unnecessary it does best if there is a high proportion of dissolved oxygen and some water movement in the tank meaning power filter(s), additional powerhead(s), or airstone(s) should be employed as necessary.

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.
