This 14cm speciemen may be the same species or not. It was caught in a local fisherman's net in a deep (>2m) section of the main river

I believe these are B. balunga.

Cyclocheilichthys sp (C. armatus maybe?)
Image

Anyone got any thoughts on the cyprinids in the previous posts?

On to the Balitoridae... Great little fish to observe and photograph in their natural habitat.

Gastromyzon cf ornaticauda
Image
Image


Gastromyzon cf lepidogaster
Adult:
Image
Image
Image

Sub-adult:
Image
Image
Image
Image

Protomyzon griswoldi (I think)
Image
Image
Image

That is the lot I think. I have some underwater videos as well which I'll post once I've got round to editing them.

This is actually as benign as it gets because it had been exceptionally dry. After rain, the river rises by several meters and turns into a raging brown torrent within a few hours.

Impressive. I was just noticing how in you video the fishes' tails were curling in the current. Thanks for the info.

Cheers, Eric
