You're welcome. Stick to one type of dart frog. The more you have the more likely they are to breed for you. One chart I saw, stated if you have 8 or more the odds of a mated pair are 100%. The best choices for first dart frogs are Dendrobates auratus, D. azureus, D. tinctorius, and D. leucomelas. All relatively hardy, large (for a dart frog,) and outgoing. Dendrobates tinctorius comes in a wide variety of colour morphs, so that may be your first choice. Try not to mix the different colour morphs. You don't want to produce any "mutt" darts.
