Hello! 😀🐸 It does depend on where you live so please feel free to send in again with more information! But that size tank would suit a smaller frog, and if the tank is taller than it is long, then an arboreal frog may be best! If you live in Australia then I would suggest probably 2 or maybe 3 Wayne-frogs (Litoria ewingii) or something of similar size (2-3cm) available in your country! I hope this helps, here is a picture of Gumby enjoying his butt-bubbles to help you….!
