whats eating my LPS corals?

[Saltwatercoral2]

So for the past couple weeks, I have been losing some LPS corals. The corals are thriving, then the next day the coral is completely gone from the skeleton.

I have a 2 head frag of hammer coral, and 1 is completely gone this morning

Have lost 2 heads of frogspawn, as well.

Before the lights went off last night I have a Green bubble coral that is on the sand bed, but it was knocked over, and a frag of Orange sun corals was moved.

All of my corals have been bought from Liveaquaria, and were in my tank for a few months now.



My stock list is:

White barred shrimp goby, with a Tiger pistol
2 Clownfish
2 purple firefish
Cleaner shrimp.
A few snails.

All my parameters are where they should be as I have tested several times and had a buddy check them as well with his test kits. I have 2 XR 15 radion pro's on my tank which is 36" x 24" x 16" tall

Any ideas? The tank has been up since June of 2015, I started with all dry rock. Whatever is doing it, is only touching corals that are on the sand bed, The stuff that is on rock's has not been touched.

I suspect it is either the White barred goby, or the tiger pistol.

Did you add any live rock to setup your tank? If so it sounds like you might have a very bad hitchhiker. I see you used dry rock for setup.

If the skeleton looks completely bare then you might want to look into Polyp Bailout. While this is not necessarily a good thing, it can be a form of reproduction sometimes. If those polyps can find a spot somewhere in the tank where all of their requirements are being met then you might be in luck. (I wouldn't count on it though) GL.

I didn't add any live rock at all.

I meant to add to my original post.. I had a green hammer coral,, and Half of it is gone as well.. I don't know. I'm puzzled.

I have seen a few times, the Goby nip at my bigger frogspawn coral, but there isnt anything missing from it.

From my experience coral from the euhpillia family are pretty susceptible to losing flesh, are any other corals dying?

Basically all thats in my tank is an Anenome, 2 Frogspawns now, 2 bubble corals, some ricordea's torch coral, and a few different hammer corals.

Loosing flesh is usually a slow drawn out process. If this is the case you might want to look into Brown Jelly Disease/Syndrome. If the polyp just up and disappeared overnight leaving a bone white skeleton then Polyp Bailout would be my guess.
