This morning I woke up and noticed a little snail crawling along on the glass. I removed him and several others i found on plants, most of them were still very small, about the size of the eye of a needle. I put a snail trap in to hopefully catch any I missed. What else can I do to rid my tank of snails before they get out of control? And is there a way to take care of any snails or eggs that may be on new plants before I add them to my tank?
