I am on the 3rd week of a fishless cycle, and looking at the tank this evening, I have noticed some small snails having a party on my conch shell. one of the plants in particular has about 15 of the little darlings still asleep by the look of it. is there a way to get rid of them now ?? OR do I wait for the arrival of the fish, which I hope will be saturday if readings continue to be good. Also is there a variety of fish that eat them or not. Obviously I am new to this game . Many thanks. All 5 plants came from the same source which is a local small aquatic centre.
