I have this ONE Yellow tail Damsel who also acts like that and he is mean, he think his the leader and I have bigger fish then him which donâ€™t scare him. One thing I have read from a post was not to use damsel to start up a SW
tank because you would never get them out. I wish I had read that because starting it up. Man is that so TRUE. With my 92gal & 90lb of rock it was hell trying to get them out that we just gave up, so they are still swimming around.
