Hello guys,
I have a red cynarina that looks awesome most of the time. While the lights ares on it gets huge, looks nice, colourful and healthy. However, when the lights go off (mainly during the late night), while it releases its tentacles for feeding, I can see a mark on it's body that comes from the side and now is reaching it's mouth. I noticed it is getting bigger. Firstly I thought it was dividing, but now I am getting worried. Notice that on the plane that the mark starts the coral does not release tentacles. Have anyone seen something like that before?
Thank you!
