Alright so today I came home with a new tank addition(frag) and was acclimating it and had to do other stuff in the meantime while it did..well it acclimated for a gooood amt of time since I forgot to add it to the tank [smilie=surprised.gif] until i remembered when I was getting ready for bed. Tank lights were out already. Sooo when I went to go add the coral to the tank I turned the lights on and saw a slug lookin thing that looked like a snail w/o a shell. Not sure what it was but its bothering me right now. Ive got a lot of money into coral I got in my tank and dnt want anything to end up missing! It was greyish whitish color and had a stripe dwn the center of its back. It went into a rock when the lights came on. So after adding the coral into the tank I turned em back off and waited a while to go back and turn them on, saw it again on a different rock near the bottom which Im sure was another one of them. I wasnt able to snap a pic b/c by the time i grabbed the phone it went up into a rock under my chalice.. Its the first time I see it and my coral has been in my tank for a while with nothing missing....yet and hopefully nothing does. Anybody have an idea what it could be? I'll keep a look out again w/ camera ready and see if I can snap a pic.
