These two frogs always stay in the water- would probably go great in a fish tank. One is about 2 in. (it's a GROWAFROG if you have any idea what that is) long and the other is about a 1/2 inch long (an american dwarf frog). I'll give you a 10 gallon rectangle tank, the two frogs, and what food I have left for them for $10 bucks. Call 208-201-1196 or email me with interest at idahocarrot@gmail.com
