I have a juvenile yellow coris wrasse in a 20 gallon frag tank he’s around 2 inches and he seems cramped.. if I were to add him to my main display tank Wich is a 54 gallon Red Sea reefer 250 it measures 36”x22” ish. I had plans on getting a pink Margin fairy wrasse. Would there be any issues with these two in the same tank? I hear yellow coris are relatively peaceful. Only inhabitants are a body and pistol shrimp (slowly sticking this tank)
