I know this thread is older, but I just joined.
We have a 3 stripe damsel and I just love him. He is too big for his britches sometimes. lol. We have a lion, trigger, 3 stripe, and yellowtail blue damsel, some hermits and snails. The only ones he can bully are the hermits, which don't pay much attention to him, and the other damsel, who is scared of him. We had a second yellowtail, but the other 2 damsels killed him.
He is very funny though. When you clean the glass or scoop something out with the shovel, he attacks it like crazy. He's an extremely bold fish. I think he thinks he's a trigger. He follows the trigger everywhere and eats anything the trigger is eating. We feed him mostly pellets and silversides.
I also have a question... Does anyone else's make noise? Ours seems to get very excited and swim downward very fast and makes this trilling noise. I don't know if it is the fish making the noise or the way he swishes the water.
