your right. its exactly the same as a 10 gallon, except taller. i got it outside a reptile store in a bargain bin for 10-15 bux.
the standard 10 gallon toppers fit fine.
vines are attached with twisty ties, and the cork bark hollows are held in place by the vines.
the wood pieces are also held up with the vine, and tied securely to major supports in the back with fishing line.
that tank is for WTF, and they love hiding in the top ivy now thats its grown in fully.
thanks again guys!!!
