This evening I went to check my tank which is fully planted. I turned on the light and took a quick look at everything and thought everything was great. I then noticed something really tiny, about the size of a pencil tip on the glass. I examined closer and noticed that it was a snail. I don't know anything about snails except for the fact that if they go unchecked they can overpopulate very quickly. The shell was a spiral shape. I removed it and closely checked the rest of my tank and didnt see any other snails. The tank is fairly new. It just finished cycling as of last week. Substrate is clean and I don't overfeed my fish. Water parameters are also in good shape. I have heard that once you have snails there is a very high chance there will be more. So, should I expect to find more snail? What should I do? I don't mind having a few snails as they can be beneficial to the tank but I don't want my tank to blow up with snails either.
