Ya know, I've been thinking about doing and indoor tropical pond for a while, I just havn't had the money, time or space to do it... maybe someday. I wanted to put a glass insert or some kind of port window in it though so you can get both the above look and profile. Stocking I was thinking about doing some schooling fish, maybe silver dollars and then basing my larger fish on what couldn't eat them. South american theme and I wanted to do some hanging plants over it. I've seen ponds with arowanas, aropaima's, RTCs and other large SA species.
