I know shame on me for impulse buying! I bought an american bull frog tadpole. It's in a 5 1/2 gallon tank with a filter and 2 goldfish. I realize that when it gets bigger I need to take them out.

What size tank will I need when it's full grown? How do I create a half and half tank? How would I keep the water clean?

Oh by the way my name is Amber, I'm 20. I ride horses and was an expert frog catcher as a child
