as stated I would like to know what these wee beasties are and if they are a good thing.
I got it Field. Gave me a laugh. I'm going to agree with detrivore/detritis mites. They are more or less harmless. If they got out of control in numbers, they could stress your frogs but that would be pretty rare. They will eventually end up in every viv but you should strive to keep them out of your bug cultures. Some frogs particularly like them and will ignore other food items until they have eaten any mites in site. Particularly Pumilio seem to suck them up like candy!Sorry...it was a bad joke referencing a recent thread (I'm sure a few people will get it).
