GSM on mission to kill coral

[duncaholic]

Seems like my GSM has decided she doesn't like my corals especially LPS. I caught her yesterday cleanly ripping off the tip of a torch's tentacle. I suspect she's the culprit in many other coral kills such as clove polyps, montis, candy brains and I few others I forgot. This behavior sems to have started within the last three months around the time she finished beating her BTA to death. Any ideas/experience? I like this fish and would hate to have to get rid of her, but I can't just let it go. 75g reef is overstocked and as a result nitrates stay near 20ppm even with regular water changes, but other thyan that my chemisrty is solid. I test for nitrate, nitrite, ammonia, PH, alk.

I believe that maroon clownfish have always been 'programmed' to be this way. It's its nature. I've had a maroon before and had to get rid of it after 2 full years of having a great connection, I had to let go, for it just didn't stop going crazy and killing the tank. Well, sigh, maroons... great personality, turns nasty after some time..
