maybe it is the photo but the left one, just after the head, looks like it comes in or sunken belley, hope you know what i mean. For ID would need better photos but do look like them. cheers jk :thumbup:
Did you get them from Andrew Coxen? If so they will be Jari Blues. Andy is a gifted Pleco keeper and always been a succesful breeder of Hypans and now the more unusal Ancistrus'. Give them time to settle down and get established they will soon look lovely (presuming they are from Andy)
