I have a frag tank i was going to set up but since i'm getting rid of my coral, its pretty useless atm. acrylic, roughly i think 15-20 gallons, center overflow, drilled for 1 inch drain and 3/4 return, $100. text for pics and questions, 609-560-9645. Also have a 40g breeder, never used, $30, was from the petco sale.
