I bought a fluro green Trachyphyllia about 2 months back. It had a notch on its rim but I assumed it was damaged during shipping.
The coral expands during night time as per usual, but that notch never healed up. Today I moved it into my nano tank and while I was sitting there and looking at the tank, I thought I see something move in that hole, so out came the camera.
First photo shows the extent of the damage, before and after extraction. The second photo shows the "shrimp" itself. If anyone can ID it, it would be great. If you look closely, you can see eggs and I only hope I won't end up with an infestation. This guy actually resembles something I buy at the fish markets.....
