thanks alot for the info, just an update for you, when i got home, it was still in the same spot. before coming to conclusion of its dead i wanted to take a look and see if it actually lost its head or what happened so i had to totally dismantled my live rock cause of course it buried itself in under the rock, after 30 mins of making a big mess and trying not to stress my other fish i manage to get a good grip of it and pulled it up near the surface. he still had a body it must have sheded it skin but the problem was it was leaking like a mucus or sumthing from the body, i bagged it in the water and took it to my LFS. and they said it was dead, it wasnt moving at all. i guess thats what happens when you try and taking care of sumthing without knowing about it. RIP amomone. Much appriciate the help guys, there is a positive out of this experience though, when i was at my LFS i bought my very first piece or coral and an flaming angel.
