ID need for evil in my tank.

After a few SPS deaths I spotted these things on 2 of my coral, a hypno and a acro. THis is bad isn't it?

This one looks like its spewing white threads.

Looks like a flatworm to me...

they don't move they look like egg sacs. The corals that they grow on don't show a stress and are growing well.

Have you tired removing the corals you see them on and letting the coral dry out a bit. Flatworms will look wet on a dry coral. It might help you see if there is more of them or help you figure what they are.

looks more like a disease one of my corals had ( similar to brown jelly ), jim reccomended a iodine dip.

is the lump a hard lump?
it looks like some form of burrowing creature.
i had one once before on an acro,i never did get a positive ID but it sent out a string type sweeper that stung the coral in the imediate vicinity of the hole.
kind of like a version of those burrowing filter feeders with the tiny fans you get in acro's

I just got over a rampant infection/ RTN where I lost two frag and two colonies. Again these corals that have these sacs are healthy and have no recesstion even under the wierd growths. All these colonies were dipped throughly.

Those are NOT AEFWs that is for sure

I also remember a meeting where someone had pictures of an sps letting out a bunch of sweeper like tentacles to attack another sps that looked just like that, is there another coral close to that one?

Are you sure it's not one a Scypha sponge? Melev's got a pic of them and I have a few in my tank. They are reef safe.

Some weird stuff is goin on here. I just noticed a piece of lobed leather is all chewed up and dieing quickly. It was all good two days ago when I las looked. That kinda rules out and kind of SPS eating buggies. I have no idea at all why Im losing corals. All params are normal. The only change is I threw in a new bag of ferric oxide (spelling) after I lost the first two frags. Im just stabbing in the dark here. I really think after seeing all the deaths and the way it moved from coral to coral it looks like a pest of some sort. And I think they are coming out of these sacs above. The sacs are no mobile but they dissappear and new ones pop up other places on this one Acro.
