Just picked this pair up last night. I am thinking they are the normal form of Ancistrus cf. cirrhosus. They were being sold as Hypostomus plecostomus for $4. As I was all but 100% sure they are not Hypostomus plecostomus I went ahead and picked them up. Any ideas if I am correct on my ID or are they something else?
A few pics. Sorry for the bad quality. I was having a very hard time getting my camera to focus on fish this small.
