Yeah. Great fish, provisionally. Highly secretive and nocturnal. If you put it into a tank with lots of live rock to hide in, odds are you'll never see it again. Very hardy, very disease resistant, largely inoffensive but it will eat small fish and shrimp. Doesn't show up in the trade very often, I think I've seen four offered in the past 20 years.
The best way to keep one would be in a species tank with -very- subdued lighting, in the hopes of getting it to spend more time out in the open. I think one would largely be fine in a reef tank, but you'd never see it.
