hey so I want to get poison dart frogs but I don't know what a good species is to start with. Is there a species that can go in a 10 gallon tank? I've seen people on you tube keep dendrobate azures in 10 gallons in groups of 2 to 3. and are there any arboreal species that will be active ? because I have an extra exoterra 12x12x18 tank I would like to use for something.
