Scorpaenidae is pretty large family with the "lion fish" acting as the "flag ship" for it. I'm no expert, and I'm not sure where the boundaries are for what makes and what doesn't make a lion fish, however, there are eight that I know of in that family that fall under Pterois and Dendrochirus. When you think "lion fish" those two groups are what come to mind.
