This aquarium is perfect in every way. But it was very poorly packed. This is all glass with a glass lid, it is all in a thin cardboard box with absolutely no styrofoam or any kind of packing. . Mine arrive shattered in pieces. Even the light fixture was bent and damaged. Why would anyone package glass this way? It was not the fault of Chewy at all. It was the manufacturer and FedEx who mishandled it, Chewy immediately sent me a replacement but I am not too hopeful it will arrive in one piece. I will update when it gets here. Customer service is the best.

Leaked after a month of having it set up.

Bought this for a birthday present and have had it set up for a month and it has started a very slow leak and cannot tell where it is coming from. Don't recommend.
