I have a female Osc clown and she has bonded well with the Anemone, but when I have added another clown: she killed it in less that 12 hrs. I put an arrow crab in the tank two weeks ago, it had a molt and she killed it, while it was vulnerable. Has anyone else had a problem with a clown wanting the tank and anemone to itself? I have more than one tank, but I would like more than hermits, 1 clown and 1 anemone and a live rock, any suggestions?
