Plexyglass Tanks can be larger than Glass tanks, but I don't think your bound to get a 30,000 gallon tank any time soon, Plexy glass will scratch, but that can be buffed out, the only real problem is clouding IMO. Glass in heavier, and will probably last longer (although after a long while you may end up with some of those horazontal lines that you see in glass windows, thats becauseglass is acctually a supercooled liquid, not a solid as most would have you believe, but I digress)
Goodluck to you (and I think the eclipse is a good deal)
