last night i saw that my single pond snail had laid eggs some time ago because they had hatched. there were several white snail babies, and 2x as many with shells, and today all of them are gone! even the adult snail! any possibilities to their whereabouts? i haven't done a complete search of my tank yet (i haven't checked under the gravel for babies nor in the most secluded parts of my ornaments) or is it possible my mbuna cichlids ate them? however, they adult snail was W-A-Y too big to fit in their mouths, so any guesses?
