I wouldn't be too worried about an acrylic aquarium failing on me. I can't remember precisely what the factor is, but that plastic is WAY more sturdy than glass. It's flexible, you know. I've got two acrylic aquariums that I use on a regular basis and they're tough as nails. I moved recently and one of my macho helper friends somehow lifted it, with all of the sand still in it, from a support brace across the top. I saw this happening and was sure it was going to break. Nothing. It's got very happy Oscars in it now.

Have a great time if you get it.
