great link lupin. There is so much varied info out there of which all opinions are different on these snails. Its interesting to read in that article (which is pretty much what I observed) that the eggs hatch/dissolve upon leaving the female. I am keeping them int he following parameters and they are very active, eating well, and reproducing: temp 80, ph 8.0, gh 6, kh8, ammo 0, nitrite 0, nitrate under 10. They are eating veggie sticks and blanched zucchini readily. I am sure as more and more people keep these snails, the information available will improve.
