I believe I have a 100 or so gallon tank, maybe 120. I have a 6ftx18"x20" fish tank- impressive I know- in my tv room. So I want something cool to put in it. My dad used to keep chiclids in it, but I think he's over it being as he hasn't checked up on the tank in months. Anyways- what's something cool to put in here? Preferably lizard and preferably something not too difficult to come across.
