I recently bought a powder blu tang and right after my water change..my nitrate skyrocketed. My Wrasse and tang started fighting and so i seperated them in my 160 tank.. I didn't think the wrasse would survive but this morning it disapeared... where the heck could it have gone??
I know if i dont find him he will ruin my water....Help!!!

He's probably buried in the sand! Wrasses tend to do that.....doesn't mean he's dead or sick. Just wrasse behavior.
What kind of wrasse is it? Was it that beat up? Do you have a new setup? Spikes should not occur just because you add a fish.
