Hi,
I just noticed two critters or something else on one of my hammers that is about 2 months old in the tank.
Looking at old photos the top one seems to have been on the coral for a long time. It looks like a small starfish when open (see first picture), but when touched it recedes inside the coral.
The second black thing seems to be newer and hopefully is clear enough on the video. Included a side picture of it as well.
Any ID and advice on if I should try to get rid of them (and how) would be much appreciated!
