is it safe to Use A 20 gallon used Fish Tank for Tree Frogs if I get the Necessities

i think what i meant was- since there are more than one size, it is not a standard size. a 10 gallon is standard all the time. there are different size covers for 20 gallon tanks, b/c there are more than one size. the op would probably want to measure the tank and find pout dimensions and go from there.
