pseudogastromyzon sp, Jim? I've got a dozen p. "lineatus" (pure fantasy-name) half a year ago which I never could identify, looking similar.

The Photo has a Pink Shade because of the Lights which are rather pink...The Loaches have a very prominent Red tip mark on the top of Dorsal Fin, but could not see the yellow color in the Dorsal Fins though. More closer to Pseudogastromyzon myersi ?
