So i bought this snail at petsmart and before I bought it I was looking for a blue mystery snail, when the employee pointed out this snail they said that the shell isn't blue but the body was which was good enough for me, I've had this snail for about 2 months the water, ph, ammonia etc.. is good I check it on a weekly basis it's a 38 gallon tank with maybe 15 small fishes in it. I keep the water temperature at 74-76°F, I've noticed over the months that the snails shell is peeling the dull Grey color and is showing a light blue color under the grey and im not 100% sure that's normal cause I've never owned a mystery snail, it seems to be acting normal and moves a lot around the night and sometimes during the day. Thanks!
