They certainly look like the pics I have seen of the species.
How big are they?
Many hillstream species are barred when young but the pattern changes as they mature.
Were they mixed in with other species? If so, that might indicate what they are.
For instance, if they came in with Chinese species, they are probably some type of Protomyzon if not pachychilus.
If they were mixed with Gastromyzons, they could be one of the Neogastromyzons from Borneo.
Maybe I should rephrase that... Has there been any cases of these guys breeding in captivity? I'm thinking that loaches I got aren't mature yet so, I've got along way togo...
