I just saw this at a LFS and bought up a whole rock for 20 bucks - are these PPE that simply need some good lighting? The skirts look a bit washed out and empty, but the mouth is green, and there are small green stripes running across the face . . . .


. These usually start off with the greenish hue in the oral disc, then morph to one of a number of different morphs (some more interesting than others). Once they adjust to your tank, I'd start moving them up a little at a time and see what a little more light does for them. Definitely a Z. gigantus, though.
