Has anyone ever experienced an aggressive anemone? We have an anemone tank, 20 gallons, which started with 3 rock flowers and a green bubble tip. Everything was going fine until a chicago sunburst was added. The green bubble tip started moving around the tank and seemingly tried to smother one of the rock flowers and the sunburst. It also tried to displace the largest rock flower, but the rock flower was bigger. Are we going to have to rehome? The smallest rock flower that got bullied looks like it might be stressed or dying.
