I've gotta agree with CrypticLifeStyle, cobitis lutheri, http://www.loaches.com/species-index/cobitis-lutheri
@QuoVadis, most cobitis are just as docile as kuhlis. Just watch out if you have any aggressive bottom dwellers. Schistura's are just one aggressive/territorial bottom dweller that I would not mix with them.
@Kitsune_Gem, try to keep the tank temp down if you can. These guys love blood worms. Beautiful loaches, nice find!!
