See em for sale all the time but i've rarely seen or heard of anyone who owns one. From my understanding... their feeding habits are similar to that of Lionfish(they like to stalk their prey) but they're slower so they should be kept in a tank without similar types of predators.

I believe they'll also eat just about anything they can fit in their mouth so that leaves out keeping small fish with them as well.

Don't have much more info on them... maybe someone else can chime in. :grin:
