Hi there,
I've a total of 4 rather tiny, but growing snails in my tank. Problem is, I do not have any adult snails in my tank at all for the past 1.5yrs. And all of a sudden, these tiny snails appear.
Can anyone explain this? Mine is a fowlr tank with no new rocks being introduced. Everything has been like that for the past 2.5yrs I have this current tank.
Cheers.
