It's a BTA that has been mistreated in some way. Too high temp, really low or hi salinity, crazy bright lighting, etc.

When they are mistreated they expel all of their internal algae. After this, they are not able to process light, so without regular feeding they start to shrink and waste away, losing all of their color in the process. It is called bleaching.

A bleached anemone doesn't usually lose all of it's algae, and if cared for properly, the algae will reproduce and the anemone will recover over a period of several months.
