Hey,
i've been keeping frogs for a few months not but they aren't quite old enough for shop bought crickets or worms. I've resorted to using woodlice/slaters that infest the back of my garden. Only problem is, they run straight into the water and drown or they hide, die and pollute the inclosure.
(Interestingly enough, the woodlice that sink to the bottom survive as they run underwater and up the side of the bowl. If anyone knows how to make water less buoyant that would be great.)
So if anyone keeps frogs or any animal that eats very small moving insects please help! The woodlice will do for now (The frogs aren't going unfed)
