healing candy canes

[Purple Platapus]

So I have this candy cane coral that got ravaged by a hermit crab... any suggestions as how I can speed up its recovery? More light, less light, etc? Also, when I bought it and for about a month, it sent out sweeper tentacles pretty much every nigh, but for the last month it didn't send out any. Does this mean anything?

Pictures will help determine the damage. How big is the hermit crab. They generally are not that large so damage is small. If the hermit is hungry it will seek out food.
