The cause is hard to pin down without a good deal more info. What you've pictured can be the result of a disease that specifically affects euphyllia corals (of which a hammer is a member of the genus), but it could also be the result of poor water conditions, flow that's too strong and impacting one area of the coral, or bleaching (too much light and/or too long of a photoperiod).

You might wish to post this question in the "LPS Keepers" section of Reef Central.

Duplicate the parameters in my sig line. "Fine" isn't enough information for us to help you, but it's likely something about your water, or some fish or invert is picking on it.
