[englishfishface]

Hi all, i recently bought a Reef1 Biorb, its a fantastic aquarium and looks great in my lounge, i have 3 fish in there, one Pearl Scale, one Fantail and what I call a window licker. I was told it was a pleco but have no idea what kind, its almost black with white leopard spots all over him. can anyone tell me what it is? thanks
