Glaniopsis multiradiata Profile*x

[Martin Thoene]

*work in progress*

Scientific name: Glaniopsis multiradiata (Roberts, 1982)

Common name: None

Synonyms: None

Distribution: Malaysia

Sexual Dimorphism: Not known. Females probably plumper.

Maximum size: 2.5 inches (7cm)

Similar to: Liniparhomaloptera disparis disparis

Care: Inhabit fast flowing streams in riffles. Aquarium must duplicate these conditions as fish have very high oxygen requirements.

See: http://www.loaches.com/hillstream_loaches.html for more detailed explanation.

With all Glaniopsis species, care is broadly the same as with other Hillstream species. All need excellent water-flow and aeration, numerous rocky hiding places and smooth pebbles and boulders to graze over. Lighting should be bright to encourage algal growth in the aquarium. Plants are not necessary as the fish do not normally encounter them in the wild, but they will help with water-quality. Suitable plants for high-flow environments are Anubias and Microsoreum. These will grow on rockwork or driftwood.

Feeding: Good quality flake, sinking pellets, algae wafers, thawed frozen Bloodworm, Mysis Shrimp, blanched Spinach, Kale, natural algae an advantage.

Water parameters: pH:7.0-8.0. Hardness: Medium. Max dh:

Temperature: 68ºF to 75ºF (20-23.8°C)

Breeding: Not bred in aquaria.

Notes: Glaniopsis multiradiata is extremely similar in general appearance to the Chinese species Linparhomaloptera disparis disparis. Both will probably appear as contaminants in other species shipments. Therefore, identifying country of origin may provide a clue to identification of the primary species.

I am pretty certain now on the ID of the pictured fish. The colouring is quite different from regular L. disparis.The belly seems far more noticeably whiter than L. disparis.

I don't want to use the picture in the original description as it's a scan from Baensch and its useage is dodgy.

I was thinking Mark found his with Beaufortia or P. fasciatus, but I may be wrong. What about Graeme?

[Graeme Robson]

I found this little chap in a mix bag of Gastromyzon ctenocephalus and Pseudogastromyzon cheni strangely enough.

[Jim Powers]

Well, that makes it more likely that yours G. multiradiata instead of L. disparis of China. Very interesting.

[Martin Thoene]

Good. that totally confirms my suspicions that it wasn't L.disparis.

Excellent!
