I have such a weird feeling about sharing pest snails with other aquarists....it's like giving someone else's dog fleas, lolI might! It's been a couple months or so, and I have yet to see one, or to see any sign of their activity in the substrate. Wonder if they all died...Maybe I'm the only person in the world who can kill off MTS. It would fit, since I also seem to be the only person in the world who can't grow valisneria.
I can help you out though, when the weather cools a bit
