Yes. I had bought a beat up pair from *****, They gave me the pair for $20 cause they where is bad shape. The bigger one died. I ended up gettign the pictured maroon elsewhere because it was supposedly killing stuff in the tank with it. I did add the big one into the tank with the smaller. the big one went straight to the anemone and the first hour bit at the small one once. After that the small one went right up to the anemone did a full body quiver thing, and did it a few more times over the next week. Now they are buddies, even sharing the anemon. the female is not agressive towards anythign in the tank.
