a 100 long spreads the weight out, it is better than a 75 beacause it is 6ft long.The issue I have is with weight, I'm supposed to have a maximum 75g. I can get away with the 80 the others are just to heavy. I got a price quote of $500 shipped to my house with glass tops. Not a horrible deal and something I'd be interested in. If I'm going to go this route anyways it does not have to be 6 foot long, I could go 5 foot something like 60 x 16 x 16 for around 65 gallons. Just trying to get the most optimal environment since the tank could end up housing a pare of mates.
