The
Pseudogastromyzon fangi seems to be the closest so far, Jim.

I just purchased the two for now. He has a tank of around 20 of them. A couple more may be in order then!
I must admit, they do look superb in the flesh. Especially the
dorsal fin like you says. Also, funny as it seems, they have settled in better with time and are looking slightly light in body colour and more active with
grazing..etc.
