I've NEVER seen an adonis called a "vampire"... The name "vampire" refers to members of the genus Leporacanthicus, who have tusk-like teeth. But it's not the case here.Down where I live, Galaxy Pleco and Vampire pleco are not the same. But they do look very simlar. The Vampire pleco (as I understand it down here) is an adonis pleco. It is more elongated and has fin extentions on its tail fin. This fish commands a pretty high price among plecos, even when small. The Galaxy pleco (as per the ones I have seen) Is a little less elongate and more thick and does not get as large (actually I have never seen one as large as the vampires.). They command a high price as well but not as high as the vampire pleco.
I think that yours is a galaxy pleco. Just cause the tail is not that long and skinny.

The pictured pleco IS a vampire pleco, Leporacanthicus galaxias. According to their scientific name, these can be called "galaxy" too, although galaxy usually refers to a Pseudacanthicus species. Well, this one could be called "galaxy vampire" or something so, to avoid this kind of confusion.
