Frogspawn trouble

[yamahadave]

Came home to find my frogspawn messed up. Its been in the tank since Jan. I was suspecting that the emerald crab tore it apart trying to get the frogspawns food, but the local store guy said it could be my levels are off. They look good to me.
Also in the tank are a yellow tang, clown, blue tang, a sea urchin, 2 emerald crabs, 2 shrimp, and several hermit crabs.
Open to opinions if you have one.
Much appreciated,

David

it would help if you could post your params. i thought mine were good too but my mag apparently was low and started killing my chalice. once i got it back up it started bouncing back

Yup,need the parameters.
I would say just by looking at the picture that your LFS guy was right.

How quickly did that change happen? If it was overnight, then something probably tore it apart. If it's been over the course of weeks, then it's probably something in your parameters.
