to find out if flowerhorns are legal why don't you contact one of the aquarium societies in your area http://fins.actwin.com/dir/clubs.php?c=13. flowerhorns can be very agressive with each other. by the time you raise fry, hopefully get a breeding pair before they kill each other off, and raise those fry to a saleable size it could be more expensive and time consuming then you realize. good luck
