My reef has been setup for around 8 months now, and I want add another fish.  Currently I have two clowns, three blue chromis, a lawnmower blenny, various snails and crabs, a starfish, and a possum wrasse in my 72 gallon reef.  I feel that things are  established and I would like to get a yellow tang. Would this be possible without stressing my reef?
