ALWAYS ask for dimensions. I went to look at a 300 gallon tank that the guy wanted $300 for. I knew by the pictures it wasn't a 300, but it was still large. I thought it may have been a 180. When I got to the guy's house, it wound up being that 5' 120 I just got rid of. Luckily it was here in Knoxville! I bought it for $50 or $100 I think!
