I recently got a Tylomelania teufel from an online local shop (Italy). Shipment was problematic cause the shop, at the last moment, changed to a very bad courier service (well known in my country) and, while i bought two of them, only one survived the delivery.
Now, the survivor snail came in pretty bad conditions, at least 2 cracks on the shell and a strange thing attached to the side of her head but at least she is alive for now and i would like to save this amazing creature.
That small white worm-like creature move very slowly but remains attached to that location. Below him, as you can see, there is a strange organic mass that have the same color of the worm but i have no idea if it's something like a sore/ulcer or a worm's egg sack. My first idea is a leech but i don't have enough experience to be sure about that.
I have a bottle of Seachem Paraguard but i think it will harm the snail so i haven't used it yet (and i don't think i will since Seachem itself suggest to remove snails before dosing in the tank).
Anyone can ID this creature and/or the white mass below him? Do you know how can i get rid of him from the snail?
Thanks for any help, really appreciated!
