Hello i was looking to get 1 poison dart frog.Before i begin i wanted to say that im not an idiot when it comes to frogs i can supply a nice heavily planted nice looking vivarium.I was looking to see if any darts would fit in a 5 gallon?Im not into the thumbnail frogs those are just way too tiny.Sorry if i sound like an idiot but are there any really cool dart frogs that i can put in a 5 gallon?(only one frog will be housed in there.Dont really know anything about the frogs so if you can tell me a little bit about them that would be great.-Andrew
