I have them in my paludarium. they seem to breed on the exposed driftwood. I got 2 hatchets that hunt them 24 hours a day... supposedly they are natural and not a problem but if you want to rid them, turbulent surface current is the way to go.
there are actually a few different species, not just spring tails. I have little red ones, little black ones, and little white ones. mostly white ones though.... which I think are spring tails. they jump like crazy.
Wish I could upload iPhone vids. I have a vid of these little white specs hopping on the surface of my tank. Just noticed today. Are these the Springtails for sure? Not harmful?
