I think it is hard to refer to fish according to the above categories as individual fish can be quite unpredictable as to what they will eat or pick on.

Agreed. Many fish are hit & miss as far as what they will really behave like, although I have had one in my refugium/softie tank for almost a year and he has never been a problem with any fish, corals or inverts that I can keep track of. I believe they are actually in the grouper family however mine is extremely timid. It's one of my favorite fish.

I have one in my reef tank with cleaner shrimps and hermits and it has never even remotely went after any of them or any of my small chromis or gobies. The other people that I've known to keep them have had the same experiences I've had which makes you wonder how they ever survive in the wild being as timid as they are lol. I'm sure they're not 100% reef safe but fairly close to it plus also being probably the hardiest fish I've ever come across and as beautiful as they are I think I will always have one in my tank
