So I have had a clawed frog since she was a little bitty thing. Now shes about 2 inches long and I am thinking of upgrading her tank. She has been in a 3 gallon so its been over due a bit. I'm thinking of just upgrading her to a 10 gallon tank giving her a lot of room to swim. There are 2 things that concern me about this.
1. She is an eyeless frog. The reason I got her in the first place was because the lfs gave her to me for free because she had no eyes. She seems to have been mutated that way in the egg, not lost them while she was a juvenile. Would it be difficult for her to find her food in such a large tank with no sense of sight (I realize they still have a strong sense of smell and "touch") but she has never had to swim far for food before.
2. This one is a little unrelated, but she seems to have lost some mobility in her left arm just recently. Its not paralyzed, nor does it hinder her swimming and feeding, but she doesn't stretch it as much as her right, and she doesn't flex her fingers as far. Is it possible she sprained it? Can that happen to frogs? Shes the picture of health, and always has been otherwise.

On a final note, if I do upgrade her to a 10 gallon is there any other species that can add some life to her tank? I know the feelings on frogs with other species of frogs. I would get her a mate/friend if I could find a healthy appropriately sized one. But is there any large peaceful fish that could go with them? I have her with a very large apple snail to keep the algae down that will accompany her to the 10 gallon if I do. I will also decorate it with a lot of live plants. Any suggestions are appreciated
