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!
