What will a six line not mess with?

Stemming from my other thread regarding six line offing my fish. I now have a yellow tang, female lyretail, starry blenny, and diamond goby with a six line who has killed a royal gramma and has about killed a pj cardinal. I'd like to put one other fish in the tank or maybe a couple of smaller ones. What would be safe with the other fish, but be either of no interest to the six line or aggressive enough to hold his own? I saw another post about fang blennies. I used to have a bundoon blenny. Since fang blennies are poisonous would that keep the six line honest? What about a 2 or 3 blue reef chromis? Woulld the fact they swim in the upper water column keep them of the six lines' radar? I know most of the damsels would hold their own, but I don't want to go that route. I was also thinking about getting a bicinctus clown and anemone. Wonder if that would be safe? Sorry for all the thoughts, but I'd appreciate any input. Thanks!
 
If the clown stayed with the anemone that would probably work. Any tangs that weren't too small would work, but you are maxed out on tangs in my opinion and in all likelihood your yellow would cause problems for any new tangs anyway. Fish that are significantly larger than the sixline would probably work, but in a 75G that would be hard. The fang blennies might do better than most other small fish, but I do not have first hand experience there so I'm not sure if their venom is defensive or for catching prey (I doubt its the latter). I think the chromis would likely be harassed, but since there would be multiples it might spread the aggression enough to allow the new fish to survive long enough to become established. Unfortunately most fish that will definitely hold their own are either not very reef or other fish safe or both.

Personally if it were my tank I would do one of two things. I would either remove the sixline to a time out tank, reaquascape, add the other fish you want, allow them to establish and then reintroduce the sixline, or I would just remove the sixline and then add whatever you want and not have to worry about it anymore.

try rearanging your rock work some when introducing a new fish to the tank. that worked for me when i had a bully in the tank.

my 6line is great, i have never had problems with him. only time i ever had a problem is when he tried to nip at a turbo snail and the snail closed up with the 6lines mouth stuck in his shell....the 6line almost died so i had to break open the snail shell to free him.

anyhow, usualy anything bigger then the 6line usualy is safe from him. but all fish are different and will have different temperments.
