Back left corner is smashed. I have fish waiting at my other home that need to be moved so I can show my home. Took 8 1/2 weeks to get a broken one, and I need it ASAP. Not a happy customer. By the way my fish are salt water, very delicate, and I have already lost $200 worth of corals due to lighting not being adequate since I am not there morning and night to turn them on and off. If the fish I have die, it will be an additional $500 replacement.
