A fish for a ten gallon tank?

driftwood is fine, if you find it yourself just boil and clean it, also it can be purchased from most aquariums and if they are good it will be fine but you can always boil it to be safe. I have multiple pieces of wood in both my turtle and fish tanks and have never had a problem. As for the fish they are all good answers. i would get a few catfish as well (there are small ones avail) as they clean the tank and dont require much effort.
