In about a month or so, I'll be able to upgrade from the 20 gallon to a 70 gallon tank.

It's very, VERY difficult to find a large tank at a reasonable price here.

Even Wal Mart sells 55 g tanks for about 400-500 a piece- not including ANYTHING but the lid, light and tank itself.
I'm very excited about this. ^_^ Though my clowns have yet to show any true growth, I'll be glad to get them into a much larger home.
