I was cleaning my snail tank today and noticed and clear jelly blob on the side of the tank. It's far more raised then a Ramshorn blob. I didnt touch it as it looked a bit gross so I left it. I only have one trumpet snail so I didnt think anything at first, but then I remember Hamstaman saying that they dont need a male and female to reproduce
So I looked up some info on applesnail.net and found this on trumpet snails:
'The transparant eggs are deposited in a firm, gelatinous clutch on plants, stones or other objects. These snails are hermaphroditic and two snails are enough to get large numbers of them in relatively short time' 
Oh no........this might sound mean, but I hope Hubba, Bubba, Judas & Squirt (my apple snails) eat the eggs. I cant handle another infestation
