Can different species of poison dart frogs live together?

Poison dart frogs live in small colonies, with members spaced a few feet apart. These colonies usually consist of about six individuals, but they are not particularly territorial and tolerate living in close proximity to each other.

In captivity it is best to give the poison dart frogs enough space for their "mini-territories". A good rule of thumb is 10 gallons of vivarium space per frog; therefore a group of four poison dart frogs should be kept in a 40-gallon vivarium.
