So I bought a Klein's butterfly a couple days ago. Now I've had some odd paring off in my tank before. Ruby head wrasse and a midas blenny that went everywhere together, but that was after being in the tank a while. This time with in minutes of putting the Klein's into the tank it started following my solor wrasse all over, even hiding if the wrasse went out of site then quickly swimming over to it when it came back in view again. Now they are pretty much together at all times.

Anyone else have some weird pairs?
