I went to another LFS
today, well, not so local..it was 40 miles away
and making good on the trip, picked up a Hammer Coral frag. I have it in the perfect spot, away from any other corals so even the sweeper tentacles can't reach anything sensitive. (Had to do some re-aquascaping).
I have two peppermint shrimp in the tank and one of them has taken a liking, maybe too much of a liking, to the Hammer. The shrimp keeps picking at it which is keeping the Hammer effectively closed up tight.
I did a feed on the tank to see if that was the shrimp's problem and it left the coral alone for maybe an hour afterwards but is back to picking at it.
Any experience out there with this?
