Hi. I just setup a new vivarium for some dart frogs about a week ago. After summer I'm going to the Tampa reptile show in october. I'm very interested in the D. Tinctorius species but don't know how to care for them. The main things I'd like to know are how many I could fit in a 15 gallon vivarium(the size of the one I have set up) and how could I possibly breed the frogs when I get them. If someone could anwser these questions it would really help.
