I have a 150g tank i was using for my turtles. But i got a larger tank so this one is of no use. Im not looking to sell it, but i would appreciate a coral donation. If you have no corals, you can still get the tank. Since i have to put a price, im selling it for $1 lol. I do not think it can be used as an aquarium for fish since the turtles scratched it many times, but it holds water.
