Mystery snails
i am a relative newbie when it comes to planted aquariums and this afternoon
i discovered a tiny snail making it's way across the glass. i assume that it
was introduced to the tank with some of my plants.
should i be worried about there being more in the tank? are they potentially
dangerous to my plants? are they a benefit in terms of keeping the tank
clean?
any advice would be much appreciated...
