VERY cool, and I'd be SUPER tempted, but the risks are pretty high. Neither of us has been envenomated by any of our fish, but if something DID happen, esp. to someone else, it would be one of those things where we'd be kicking ourselves in the a$$ for the rest of our lives.
Since Renee is an RN, she has seen the unfortunate outcomes of "questionable" decisions (I'm not saying that you wouldn't be WAY better suited to keep such as fish than the average aquarist, as would a couple of other folks we know). The stingfish we keep are dangerous, but extreme pain is different than death.
If you DO get it, let us know, because Renee would LOVE to come down and photograph it. You truly happened on a beauty there!
