Ok so i got a Hector Goby maybe about a week and a half ago. (We recently got new rock). He chose this little cave in one of the new pieces of rock. In about a day he disappeared. No remains or anything. Three or four days ago we got a pair of clownfish. One of them chose that same cave. He went missing for a couple hours... Then we saw him but just then something pulled him under the rock! I lifted the rock and he shot out. He is very beaten up so i netted him and have him sitting in the net at the top of the tank. Not sure if he's gonna make it :/ I tried to block up the cave with some small rocks. We had seen some centipede looking thing in the cave. I have no idea what it was. Please help! What is this mysterious killer in my tank. (I am not sure if the "centipede" is related or not) I don't know what to do and I am very worried!

I see another thing now... I see this clear worm looking thing which has surrounded most of the cave. For the most part it has covered itself in sand and stuff but it has a tip at the end that is searching around and sticking in the sand.
 
If you are sure the culprit (maybe a predatory worm) is in that rock I'd just chuck it in the trash and get another rock.
 
take the rock out and start drying it out. it should start making its way out of the rock looking for a better environment
 
What kind of corals are on the rock? Just move them if you can. I'd do whatever I could to remove it since I wouldn't feel comfortable with some random killer in there.
 
Centipede looking thing....most likely a Eunice worm, nasty looking and nasty to fish and corals. I have one and it has taken chunks out of the fins of several of my fish and it loves munching on my prize zoa's. Like you I can not get my rock out to get at the worm due to 8 years of coral growth bonding all the rock together.

Soon though it will be payback time for all the trouble it has caused as I am upgrading to a bigger tank :thumbsup:.
