I encourage you to read more on dart frogs to know more about the specifics of keeping them in captivity. Or ask as many questions as you want here. They have specific needs (like all different species of frogs of course), and reading about these needs will give you a better idea if these frogs are actually for you.
If you want to know more on leucs, DonLisk could be a great resource!
