I've had 4 snails (that I've seen) in my tank now. 2 tiny ones last week and then today I found 2 much bigger ones. I was horrified. I also don't think they're they same species as the first 2.
Anyway, I sucked one of them out and then noticed the second a while later. I decided to "do it in a minute" as you do coz I was watching something. I noticed out the corner of my eye that my Platys were flapping around looking excited about something but thought nothing of.....went back 2 mins later and the snail had dissapeard from the side of the glass. So I think they ate it LOl.
I have LOADS of eggs all over my sand, I'm actually surprised I haven't seen more snails. I think they must have come in on the plants coz I certainly do not overfeed. I'm now wondering if I have had a lot more and my Platys have just eaten them before I've seen them.
What concerned me though is these 2 snails were much bigger than the first 2 and it made me wonder how long they'd been in the tank and how I hadn't seen them before. It's not a big tank and I'm obsessed with looking for them!
