I got 5 ramshorn snails the other day to start breeding for puffer food. I've got about 10 bunches of eggs already, anyone know how long it takes for the eggs to hatch???? Also, one of the snails came out of it's shell and I can't find it now. The shell is laying on the plant empty. This morning when I checked, there was what looked like a snail without the shell laying on the ground next to one of the other snails but it's gone now. Anyone know what could have happened to my snail????
