It cant be the crushed coral he would have scratches? Not a single scratch, all fins were perfectly fine just a missing tail, when i took it out and it was foating the picasso seemed to be triggered by it and it did like a little dance$75 wasted and a wrasse to the graveyard. I wonder which is worse Most burrowing wrasses need fine sand. It sounds like the poor thing got its fins chewed off because it couldn't completely burrow in to substrate.
"The wrasse is 80% submerged in the crushed coral"
Picasso triggers are some mean SOBs. I had one 3 inches long that would defend nori against a large purple tang, naso and a much larger niger trigger and all other fish. They remind of Pitbull's. Awesome pets that do not play well with others.
