There are no matching Garra species (with pitures available, anyway) listed on Fishbase, but with the possibility of this individual being wild caught (I'd guess only colour morphs are bred in captivity), it's pretty safe to assume it's either a deformed CAE (which seems quite likely given the outstandingly similar pattern) or a Garra species that you aren't likely to ever identify. Treat it like a CAE, garras require almost identical care.
