I have a pair in my 225. They never leave each others side. However, I had an original one. I then added a pair. My established wrasse, accepted the smaller of the two, but was out to chase away the larger. It was removed and the other two remain a pair.
I also have a spotted leopard wrasse that lives in there also. All get along well. I removed the larger leopard when adding the six lines and then re-established the leopard after.
