Go for the 180 gallon???
I have a 135 I got for $60 (Not bad!) last year and I've been patiently waiting to set it up. BUT, I think I want something bigger lol. There's a guy by me trying to sell his 180 for 400 OBO. He recently downgraded to a 125 so I'm wondering if he might take a trade!? Worth a try right, if he says no ill offer 200 lol
