Just purchased an adult red coris today acclimated got prepared to put into the DT my melanurus flashed up checked him out swam around him and would bolt to him a couple times to looks like peck at him. I just turned out the lights now the red coris is out and about swimming around while the melanurus is tucked in the sand. Should I expect this to go on for a couple days for things to settle down or what? These are the only two wrasses in my 80g
