Regarding thumbnail breeders, I have 1-2 forms of Ranitomeya imitator available on an ongoing basis. Right now I have 2 races available for sale - Tarapoto and Varadero. I have 3 Tarapoto ready to go and 1-2 Varadero I would sell right now. In a month my other Varadero froglets will be old enough to sell.
