looks like an internal overflow box covered in coralline. Either that or it is a clear internal overflow with something in there making a boat load of bubbles.

yes that is a over-flow box but if your talking about the thing that is making the bubbles attached to the over flow box ummm thats a good ? It almost looks like a air stone but i cant tell if the is a air line attached to it but who cares its a real nice looking tank
