My bigger clownfish suffered a loss as her friend that she had paired with got eaten by a gorilla crab. My anemone has been continuously moving and it might be because of this. My bigger "assumed female" clownfish has been aggressively attacking my new smaller one and I even saw it lock gills this evening. What steps should I take? I would prefer to be able to keep both, any strategies? Should I return the bigger one as she is the only one showing any signs of aggression, or return both and get a new pair that have been kept together? What is the best plan of action in this situation?
