Lionfish, in their natural South Pacific habitat, are amazing, beautiful fish, cunningly using their magnificent fins to corner prey in crevices on the reef.
Lionfish, in the home aquarium, are an incredible display, their flowing fins and graceful movements bringing tranquility to the mind.
Lionfish, introduced into the waters of Florida, the Gulf of Mexico and the Caribbean, are a plague of epic proportions. Whether they were introduced by irresponsible fish-keepers astonished at how quickly they grew big enough to devour all the other pretties in their home aquariums, or whether they were introduced when Hurricane Andrew flattened some of the importers' facilities along the Florida coast, they're there now, and they're taking over. Big time.
Some of the first folks to notice were commercial black sea-bass fishermen, who wondered where all the juvenile bass had disappeared to . . .
Local dive groups now hold "lionfish rodeos", competitions to see who can remove the most / largest lions from Caribbean reefs. Folks are encouraged to eat lionfish in the Western Atlantic, and you know what? It's pretty darned tasty stuff. (I've had it in a ceviche prepared by an amazing chef.)
_Nobody_ has - or should have - a problem with lions in the South Pacific, and nobody should have a problem with lions maintained by _responsible_ aquarists. Not all aquarists are responsible, though, nor do we have a reputation for responsibility, so there's an uphill battle to be waged. Back in the early 80's, I can remember being saddened by finding a magnificent adult blue-ring angelfish ... dried out on a beach in South Hampton, New York. Things like that shouldn't happen - and making sure they don't should be part of the responsibility we accept when we fill a box in our home with salt water.
