PetSmart right now has a 125 gallon with hood, lights, stand and heater all ready to go for $525. I would have a hard time selling out $600 for a used tank that offered no kind of guarantee at all. I also would want to stock it as I please, not as told what I had to have. You will not be liking blue gravel and fake decorations for long, either. Just my opinion but it would be a huge no for me.
