Here's an post from several months back on this subject:
N-E CICHLIDS: You can get a Permit to sell and have Restricted fish in Florida. You have to apply for a permit to Have/Sell illegal fish from the FWC. The catch is that when a wholesaler gets this permit, they can only sell to someone who has the same permit within th.e state of Florida. Now, if you are an internet company like myself, I still need the permit to house the fish, even if I am not selling to anyone in the state of Florida. I can house Piranhas in my tanks as long as I have the permit. The only things I can not house, even with the permit, are fish that are banned in the U.S. all together (Asian Arowana, Snakeheads, Etc...) Black Arowanas are illegal in the State of Florida. However, I can house them in my facility under the permit. I would say; it is hard to get a permit, but not impossible. The FWC comes out to your place to inspect the holding facility for them. If you get caught selling to a non-licensed person, they will take your license and fine you. You can have some of the restricted species. It depends on the type. Like for instance, the list states no Boney Tongued Fish, However you can sell and have Silver Arowanas in Florida. Talapias are illegal in Florida. That only applies to certain types of Talapia. There are many different types of Talapia. Contact the FWC for a detailed list. Most people stay away from restricted fish, in general, because they don't want to take the chance on what species are illegal and what are not. Safer that way
