Gastromyzon scitulus?

[Hendra]

Firstly I thought they are G. ctenocephalus but from the new paper (probably) they are G. scitulus.

[Hendra]

This undescribed Gastromyzon have similar coloration of caudal fin with (newly describe) G. crenastus.
Probably collected in the same stream with G. scitulus (but perhaps different stream with locality where G. scitulus firstly described) since they found together in the same shipment, not just to my hometown but also at another country. They looks quite wide spread around the world !! :scratch:

Undescribed Gastromyzon from south Kalimantan. Have (very) variable pattern of body !!

"Mouthworks"

Great pics!
One thing I have often wondered about these fish. If you have several species in one stream, do you find them in different habitats within the stream or do they all live together?

Superb pictures!

Love the "artwork" from the G's.

Thanks

Jim, in my experience in fields I never found more than 1 species in the same stream. But from the new paper of Gastromyzon, they found together in the same area. (see the data of examined material, they have the same locality and GPS data)

Graeme, here another “mouthworks” in different tank. There is 2 different type of patterns, first, same as in G. sp. SK01 have continous arc line form meanwhile the other is interupted arc line. Since the interupted arc line have more than one size, its clearly more than 1 specimens involved. And meanwhile there is 2 different species in the tank, perhaps its showed the different works results from the different species??

Yes Hendra...your undescribed species is something I've had for quite a while. I recently took these pictures.











These are nice fish that came in with G. scitulus. Now you have me seriously lusting after SK01

This SW01, probably will have truncate snout on bigger fishes?? I have "feeling" if this species have relation with G. ridens and G. crenastus
