I work at a LFS and I have a regular saltwater customer that has been raising sharks for about 5 years now, and is in the position to build an extremely large pond for a new aquistion. In large we are talking about a 50,000 to 75,000 gallon tank. My question is he came to me yesterday asking about aquiring a Hammerhead pup. I do not claim to be well versed in the care of sharks as my specialty is reef fish, freshwater, reptiles, and small and furry. So can anyone tell me whether this is an importable shark, and if it is what types of permits and such would he need to aquire in order to obtain one. The tank would be made to be an indoor swimming pool type of addition to his house. He is financially capable of creating whatever the needed habitat is and has the experience to manage something of this magnitude in my opinion, which probally does not hold much credit due to my lack of experience with sharks. Any input would be appreciated including blunt this is a bad idea advice. He does not want to aquire something that will only be hurt as a result of keeping it.
