I envy you-- Enjoy them. It will take the pair some time to breed successfully. It seems that pumilios (at least my Bastimentos) need some time to get the whole ritual right in order to lay fertile eggs. There were a few attempts at unfertilized eggs at first, worth watching, if you can catch it. I once witnessed an impatient male, waiting for the female to "finish it up," root under her with his snout and toss her across the tank so he could "fertilize" before she was finished laying eggs. Even young, anxious dart frogs can have premature ejaculation problems, I guess. Later, they raised a tad and the froglet had SLS-- no front legs, so of course it died. They are currently into another attempt. Patrick told me that quite often young breeding pumilios will produce froglets with SLS, but later ones will be fine. I'm still waiting for the later ones. My pumilio tanks are pretty densely planted, can't see into the bromeliads like I'd like to, so don't know everything that is going on without interferring too much. I'm no expert on pumilios, have just kept some and observed them, and mine have not died or gotten sick yet, and still seem to be "in love," at least once in awhile. Enjoy yours, and let us know how the twitchy female does. But DO separate her from the others, whatever you do.
