Dionigi, Well, thanks for doing that research. Is there any way you could get that picture to me? This afternoon I decided that it was definately not any sort of otocinclus because it has a fin that none of the oto's have. (It is the small one behind the dorsal fin, sorry, I don't know what it is called.) Bulldog pleco... What else does it say about their behavior? Are they rough on plants? Thanks again. Alok
