Yep,Megalodoras urinocopus.Lately I have been seeing them labled as some kind of Raphael which is unfortunate.Megalodoras and Raphaels are related but they are two totally different species.....and besides Megalodoras is a cool enough sounding name in it's own right.
Anyhow,enjoy your young gentle giant.They are harmless,rarely come out during the day and can eventually grow quite large....well over twelve inches in length.
