Come Monday I will be the proud owner of a 6" Peacock Mantis that a fellow reefer in my area is selling. I am purchasing the Peacock along with the tank and all the live rock and sand. What will be the best way to make this move less stressful for the Peacock? The seller is roughly an hour from my place and I would like to only make the trip once and get it over with. Do I leave some water in the tank (29 gallon cube) and leave the Peacock in there or......?
