Crocea wasting away in one night?

[RRaider]

I have/had an electric blue crocea who was fine last night when I went to bed at 1am, 11 hours later and he is closed up with his tissue basicly melting. I've had this guy for over a year. Checked all of my params and everything looks good. All of my sps and lps are fine. Is this common?

I did have a very large flat worm attack a snail about 4 or 5 months ago. I squirted boiling water into the hole in the rock where he retreated but don't know if I got him. I don't have any angel's, do have a coral banded and maybe an emerald or two.

Any thought or ideas?

Ok, thought I would add more info

#1 Calcium 400 ppm
#2 Salinity 1.025
#3 Alkalinity 9 dKH
#4 Ph 8.2
#5 Magnesium 1350 ppm
#6 Temp 79 deg F
#7 Nitrates 0
#8 Nitrites 0
#9 Phosphate unmeasurable
#10 Ammonia 0

I have two clowns, a Lubbock's Christmas wrasse, very small hippo tang and a Royal Gramma. Emerald crab (maybe, haven't seen him in ages), coral banded shrimp.

No corals close to him, corals are predominatly sps with a few lps and a couple of rics on the sand.

Clam was about 12" under 250w MH.

clam is closed with a small gap, I can tell a lot of his flesh is gone, looks like it started on one end.

im willing to bet it was the same flatworm that ate your snail ate your clam.. was it big flat and brown with spots

yep just like the pictures on Melev's site and elsewhere. Anyone know how to catch one of these things? I've had the tank well over a year and i've only seen it once and I spend hours observing and fiddling with my tank.
