Curious thing happened today. I was looking in my most established tank today, observing the new algae growth on the driftwood when I noticed something odd clinging to the wood. I looked closely and to my horror it was what looked like a pond snail. I noticed two more of the buggers clinging to the driftwood nearby. We picked them out and sent em packing but Im confused as to how they got there to begin with. Nothing new at all has come into any of our aquariums in months. No plants, no fish, no deco, nothing. We only keep ramshorn snails and have never had pond snails up until this point. How the heck did they get there?
