[ThRoewer]

My bicinctus are not overly aggressive towards other fish and I found the same to be true with many of the clarkii variants and lookalikes. Many of those are also not overly picky with their host anemones and take pretty much everything. Some will even accept anemones that are not host anemones. I had once a chrysogaster that forced himself on a Mediterranean Actinia equina.
Skunks, on the other hand, can be as aggressive as all the others.
In general I found it depends more on the other fish than on the anemonefish whether there is trouble or not. But with just a damsel and a blenny I would not expect much trouble.
