I have had an infestation of tiny snails for the past few months. I must have removed at least 100 of them but I keep finding more. Can they reproduce when they are this small and are they Ramshorns? I see more and more tiny babies appearing which are very hard to take out with my tweezers. A lot of them are up against the glass and are almost flat. I tried putting a piece of lettuce in the tank to catch them but they're not interested. Any other suggestions? They are in a planted 6G Fluval Edge which has only a small opening to get things in and out off which makes it a lot harder to manipulate the tweezers.
