Attack on the sea hare

[Frenchie2]

I got a sea hare yesterday to get rid of HA I have on some rocks. I placed it on one of the rock and it seemed to be feasting. Lights went out. This morning I was trying to spot it through the LED lighting but couldn't find it. I finally saw it at the top of the back wall of the tank tonight. It moved away on a rock where 2 cleaner shrimps hang out and the shrimps started to pick at the poor sea hare. I moved it away on the other side of the tank and now, my Mr. territorial raspberry dotty is picking at it (I also saw the Midas blenny do that, only once though). Should I be concerned??? Last thing I want is a dead sea hare in my tank and the whole stock gone.... Opinions please...
