I have a Temminck, I saw it on page 2 of this thread, it does not have the yellow stripe, but everything else looks the same. Do I have a female or male. It is about 4 inches long. I want to add 2 more wrasses, but don't know which ones? My tank is 150 gal. but is 48in long by 24 wide and 31 tall. Not to much swimming room. Any suggestions?
