hi there

I got this tank in a coral trade a year and a half ago. it has sat in my parents basement since then. I recently got pre approved to buy a house and am going to purchase one soon. I want to use this new tank that's been sitting in my parents basement as its way nicer then my 40G breeder tank. this is a corner bow front Fluval tank I dunno how many gallons. here is the tank its on my local fish forum you might need to sighn up to view it.
