[Out of all the fish in our tank, if we want to introduce a new fish, we have to worry about what the purple tang will do. The female gold-stripped maroon chases everyone off from time to time, but has not literally attacked something. Anyway, I got a bi-color blenny and watched for the next two weeks and all seemed to be well. Looked like nobody really cared he was there. That made me feel at ease. Well, yesterday I almost fell on the floor with laughter. I had just gotten home from work and was winding down by looking at the tank. The bi-color likes to stop on this one ledge on a top rock when he is not swimming around. He was there and the purple tang was casually swimming by. He jumps off his perch and bites the purple tang in the butt!!! :laugh long: The purple tang's reaction was almost as funny as he bolted off, not knowing what hit him. No damage to the tang, but a funny site to see none-the-less. Guess I was concerned about the wrong fish in this case. :laugh:]
