I have had a really pretty very active golden apple snail for half a year now. A few days ago I bought her a companion. A blue mystery snail. At first i thought Qi-gong was just shy, but now it is lying on the tank floor with this white stuff on it's neck.. i have a picture.

He's just lying there.. Tai-chi is still doing her normal stuff, eating plants and cruising round her bowl.. She's checked on Qi-gong more then once, and i'm afraid of her getting sick! What should I do, what is wrong with my new snail.. T_T

Thank you
Kiti

I'm not sure.. disease/infection from the new snail?

Anyway, is he dead?
