Rehoming dart frogs (vallejo / benicia)

So, I have a bad habit of rescuing dart frogs from Petco that are in a sad state, but have accumulated a few too many. Looking to rehome a one or two of my Dendrobates Leucomelas (yellow and black) and a single Azureus (dark blue). Just let me know what your prior amphibian experience is and if you can feed them.
