Im pretty sure thats a burm. If you look at the head it doesnt look like a retic head. And even a 2 year old dwarf burm should be bigger than that and dwarf burms get about 6 feet. Let alone a two year old dwarf retic, which will usually stay between 10-14 if its truly a dwarf and the whole dwarf thing is a little foggy. If your not experienced i wouldn't get it, and the only reason i would get it would be to rescue it.
