Snail update

Just to confirm that the River Snail I reported earlier has been confirmed as that species and that it is a first record for Scotland. However, I have also been told that it is commonly supplied to aquarium keepers from aquarium shops and that this is the most likely origin - someone on Islay had one or more in an aquarium, maybe several years ago, and for whatever reason released them in Loch Skerrols.
