Rich--you have re-expressed the theme I've been preaching and getting some rather snotty answers about for some time, particularly about mixing them with other Genera of tree frogs. I do not ever say "Never Mix," although I don't do it myself, and I've had some experience with keeping and raising a number of darts species individually. I just think if someone is asking the question, this is automatically too early in the person's experience to consider doing it-- for them. Raising darts separately is such a delight while you keep track of them all and learn their habits first hand. I may consider mixing when the fish in my 180 gallon terrarium die--but they seem determined to out-live my future plans for their home I will inherit if I can manage to outlive them. Even now, I'm not sure what I would mix.
And of course, any situation that will keep a dart frog healthy and alive is a potential breeding situation, and part of the fun is either watching them raise their own tads or doing it yourself. There are so far, only opinions about what should be the ethical rules of raising either hybrids or mixed morphs of a single specie together for the every day hobbyist. As a hobbyist, one can do anything one wants to do with mixing morphs. You can keep a whole housefull of mutts, if you want. Giving away, trading or even selling and representing them as something else is another matter.
