I wasn't going to get into this but ChilDawg is correct. Really, IMHO only 3-4 species of channa should be illegal, the first being the argus. But with a fish with such a dysphemistic name, it is easy to incite a panic and villanize the entire genus.And it's gross generalizations of the Channidae like the ones made in the post above that have the entire family banned throughout the United States. Truthfully, a few species are that cold-tolerant and it's just easier to ban the lot of them throughout the U.S. than to pick and choose certain species. If wildlife biologists can't tell the difference between Pacu and Piranhas, they probably can't discern between species of SHs.
