Hey everyone. When my brother moved to Dallas, he had to get rid of all his saltwater tanks. He's now moving back to the Bay Area and my sister and I want to get him started on fish again. I saw this ad on craigslist and was wondering if it was a good deal? http://sfbay.craigslist.org/sby/spo/631534976.html I have a 240 gallon but it was given to me so I don't really know the cost. The 250 gallon looks acrylic. I e-mailed the seller and he e-mailed back saying he was going to call me tomorrow morning. One of the things I'm worried about is that he has the tank standing up on its' side. I heard that it isn't good for glass or acrylic tanks to have all its' weight on one side. Is that true? Thanks, The Doctor.
