So I have 2 clutches of mystery snail eggs incubating in a Tupperware container with a lid in top with holes in the lid, the egg clutches are on very damp paper towel in the Tupperware container. One clutch is 3 weeks old and the other is a week and a half old. Tank is at 78 degrees with a lid so their should be plenty of warmth/condensation. But my problem is the 3 week old clutch doesn't look like it's maturing/developing, I don't see the eggs changing color or spots in the eggs that would be baby snails...also this past Tuesday I had a clutch that I removed because it was 4 weeks old and never changed at all so I broke it open and the only thing inside was gooey jelly like stuff...are my clutches just not fertile?? Am I doing something wrong?? Yes I do know that I have 1(probably 2) male snails in with 2 females and I see them mating all the time...so why aren't my clutches maturing/hatching??
