I thought the little pond snails were adorable at one time... Looooong ago in a land far far away.
they are impossible to avoid, and if you see two, soon you will see a hundred! Oddly in 3 FW tanks they have been reproducing at different rates, some look long and pointy like assassins(but the one I bought died) so I think they are something else, then pond snails are everywhere, and then these semi-ramshorn looking ones that could just be a different type of pond scum, uh I mean, pond snail.
When I purchased 3 ornamental snails for my first Betta tank (well his second upgrade into a 29) I was soon appalled at how much poop they produce! I think the mystery snail pooped 1
as much as my single Betta, of course in a 29 he was the only fish at that time.{{{don't know where Yoda appeared from LOL "ten times as much as"}}}
So my solution came to me as a happy accident, I rescued a pea puffer from my Ex who had him in a one-gallon tank with ghost shrimp(aka dinner).
I put the pea puffer in his own 20G and put the driftwood with anubias and ferns one by one into his tank (from the solo-Betta tank, I know not sterile but both are healthy so I risked it) and he hunts down every snail baby! very fun to watch him hunt!
