Selling a used 450 gallon acrylic fish tank. Came out of a resort. Made of inch thick acrylic. Has a few scratches, but they are almost invisible when full and easily buffed out. Has built in side overflows with 4 returns and 4 drains. This thing is massive. Would love to see someone put it to good use. Size is 3 foot by 3 foot, and 7 foot long. Probably weighs about 600-700 lbs.
