Nudibranch identification

[lilredwuck]

Found a nudibranch that is purple with bright green armour on it. Need to know if it is a good or bad nudibranch and maybe what species it is. Looks like this, but different colors. Purple body with green armour.
Found a better picture, looks just like this.

Looks to me right in the link you posted they listed it as a soft coral eater. Looks a lot like the zoa eating ones though. General rule of thumb, they look like what they eat. (usually)
