Well, I'm going to be moving from this his in three years so that meens more room. People were telling me about fiberglass tanks made by AES, they are so cheap! Its like, 800 bucks for a 683 gallon that has a large viewing window... I'm going to buy one of those after I move and by then the aro will need an update and Im sure it would apreciate a 300+ tank. They have ones from 163 gallons all the way up to 2,000 I believe. Not the prettiest (all blue with large viewing window infront) but the arow would love it im sure.
