Has anyone with mystery snails ever had one float for more than a day? I have a mystery snail going on a week of floating around the top of the tank. She is still very much alive, as she has managed to grab a decoration or air stone tube a few times to hang onto, but she spends most of her day just hanging half out of her shell being pushed around by the current. I tried putting her in a small cup with some zucchini to let her eat and catch a break, which worked. But she is still quite buoyant. Any tips on what to do? Should I take her out of the 50 altogether and keep her in a container with a lower water level? Should I assume this will eventually work itself out? Any advice is appreciated, I feel terrible just watching her float around.
