Alright so after making a trip to the PetSmart here, we decided to finally upgrade the tank to a 20 gallon )our fish and frog seem a lot happier with it), and was planning on getting another betta fish for the 10 gallon. But Dave decided he wanted to get crabs, they always drew him in, and he bought two of them. They are pretty interesting fellows, and seem really relaxed in their new home. Right now they are still babies, but will get to around 2 inches so later we may need a new 20 gallon.
