Hey everyone! I just got the best WFF culture from Josh's Frogs I've ever seen. It took a day or so, but I'll have enough to feed everyone's babies for a year! I do have a dumb question. I used the same container that I used with my small/pinhead crix. The crix could never escape out of it. The WFF walked up and out if like it was nothing!!! SO, how do you keep WFF contained to a dish/bowl/tupperwear without coming out so they can eat?
