I think my options for putting another 3g are pretty slim. The only furniture it could go is my desk (one tank is enough on it) and the kitchen window sill. If I got a bookshelf then maybe. Currently all our books are piled on top of our dressers and the shelves in the bathroom are not sturdy enough plus the steam and kitty litter would make for bad air quality for a fishy!
Aw, I feel bad for the froggies though. And I wouldn't want to buy one from the LPS to just have one since they like to be together.
Thanks for the info though :)
