Green Wrasse

[figdish]

i have a green wrasse and silly me purchased a featherduster and watched him chomp it down within a day. Had a pulsing xenia and when i got home yesterday only the rock it was attached to was left. Wasnot very big but seemed to be doing ok. Did my wrasse eat the xenia too, if so he has gotta go. How would I go about catching him w/o moving all the rock around. One issue after another but well worth it
