Hello, today I received my first 2 anemones, they are epicystis cruciferous or rock flower. And one of them at night I noticed a “bubble” in her mouth, I don't know if it's normal or something is wrong with her. I must say that I am quite new to this hobby and have found little information about it. I share some photos of what they look like at night with the light off and the bubble in the mouth. The first hours during the day it looked fine and without that bubble. Greetings and thanks
