Looking for thoughts/experience with feeding micro-fauna from a worm composting bin. I can identify the red wiggler composting worms (Eisenia fetida), small white springtails, several mite species, dwarf white isopods, nematodes and several other small invertebrates that I can't identify. I tried to take a picture but it is really hard to get good resolution of the time creatures. I'm going to try to get my SLR and macro lens out tonight to get a better shot. I would like to start feeding out of my vermicompost bins to my frogs but have not done so yet due to concerns of introducing some type of contaminant or unwanted pest. Anyone else have experience with this or thoughts on the risks?
