new fish being bullied beyond anything I've ever seen

It's terrible when things like this happen. Chalk it up to experience. You've just learned what to do in the future. The sea is a mean nasty place to be if your a fish, shrimp, coral, snail, crab or whatever. Your always someone else's lunch if your not careful. There are certain fish that take on a bad attitude toward others. Our prison's are filled with the same story. I would go to the root of the problem and in this case it's the clowns. You probably need to move them out. I have 2 little percula's that don't bother anyone. I have a ton of fish and they all get along because I introduced them in the order that's recommended. Experience is everything in this hobby. Keep at it and you'll be fine. We all went through the losses.

 

Well, he's long gone, and as an added bonus, my yellow headed sleeper died to. I don't know what happened, but saturday I had two sleeper gobies and now I have none. So, my clowns and probably six line are going back to the LFS.

 

It's a sad situation but it's life in the tank.
