coral regeneration?

[D70Challenger]

hey all, well i was curious about how long it takes for coral to regenerate tentacles. for example, my bubble coral was attacked by my peppermint shimp about a week ago and alot of the bubbles were torn off (currentley was relocated to my fathers tank), was wondering how well bubble coral regenerate. then today i saw my emerald crab rip off a few tentacles from my frogspawn and was wondering how long before that would be back to 100% as well.
thanks all

They probably won't if you don't remove the predators.
Frogspawn is fairly hardy IME, so a few tentacles is not a big deal, they'll most likely grow back if you remove the crab.
The bubble I'm not sure about.

Hello,
Most LPS corals can regenerate within a few weeks if conditions are good. I have cut Bubble corals into many pieces and the cut areas have healed in a week.
