Purple Frogspawn Frag: Questions

Ok I am a HUGE newb at this whole reef thing. I recently purchased what was described as a 1 head purple frogspawn frag. It seemed to be fine the first couple days until it was attacked by an evil shrimp :rant2: . I observe it frequently and have yet to see its 'tenticles' sweep out at night (i use a flashlight to spy) . It still hasn't returned to its 'normal' state like it was at first. Just did a water check and everything is in its proper place, no recent fluctuations of any sort. It has proper lighting and flow.

I've included pictures if that helps. The first two are close ups of the frag itself (i hand to hold it because my camera sucks - also note the branches aren't always quite that receded but have been much more so since the attack). The others are how it looked before the attack.

So to get to my questions (please also include any personal experience you've had with these corals as I could use all the help I can get):
Can it ever recover from the shrimp snagging a few of its branches?
Was this frag even properly fragged to begin with?

Thank you, that helps a bit. I'll have to research the dip. that is exactly what happened to my poor little frag.

More info. It doesn't seem to be putting out any sort of tentacle at night and recedes quite a bit more into its skeleton

I use T5HO, two actinic and two 12000 daylight bulbs, 4 LEDS. The coral has a very moderate indirect flow that (before it was attacked) just let the branches extend fully and kindve wiggly gently about. It seemed perfectly happy before 'the incident' involving the least likely of culprits, a peppermint shrimp. I know it was him because I caught him at it with a flashlight and nope, he's no camelback, straight peppermint (since been removed).
The only other frags I have in the tank are a red chill cactus coral, which after a few feedings now extends its polyps every night and is healthy. I also have a small frag of zoas which open with the lights each day (i spot feed them phytoplankton). All of them are spaced well over 8 inches away from eachother.
The rest are all in superb health. As was the PFS before the shrimp started getting at it.

should i just feed it similar to the other corals? just suck up some mysis in a dropper/pipette i have and kinda shoot near it? I have read conflicting info on whether I'm supposed to feed at night or during the day.

i'm planning on heading to the store tomorrow so i can prepare a dip for it.
