Research further before you get some. These are not your typical bristlenose plecos. They hardly will survive temperature soaring above 76 degrees Fahrenheit and insufficient supply of oxygen. Sorry but I would suggest a river system when keeping these fish. They originate from fast flowing rivers and as such, they should be kept in an environment similar to where they came from. Click
www.loaches.com and proceed to the article section where you will see more information on how best to keep them alive for a long time.
All hillies eat algae in the wild along with aufwuches which harbor in the algae. This does not make them necessarily herbivores.

I have a few of these myself in a river setup composing of 4 species of hillies. Chonhzilla, I believe I've seen your pics in another forum I think. That is a
Gastromyzon zebrinus. You get plenty of different species in shipments of hillstream loaches. A few others you might encounter are
Gastromyzon stellatus and
Gastromyzon scitulus.
