For a 300 gallon tank - it would be good as "grow out" tank for any of the common species of Bamboos, Eppies, Horns, or Catsharks. But the only sharks that might be able to be kept in the 300 gallon for their entire lives is the small catsharks (i.e. species of the genus Atelomycterus).
The Hammerheads(Scalloped & Great) can only be kept in Public Aquariums - due to the size of tanks they require and the fact that special premits to keep them, as well as the care that they need. Btw the same guidelines apply for sharks like Bull sharks as well, and most other large requiems.
Even Bonnetheads & small Requiems (like Sharpnose, and Blacktip reefs) require the highly experienced care of very experienced keepers and tanks/lagoons that are the size of large swimming pools -that are 10s of 1,000s of gallons.
Best recommendation - if really want to keep a "pet" shark. Follow these
steps. Then when your finally ready - go with a "aquaria friendly species" i.e. the Bamboos, Epaulette, coral catsharks, or the Horn shark.
1.) Talk to people on Aquatic Forums like MFK
2.) Read up on Keeping sharks - "Aquarium Sharks & Rays" by Scott Michael is a good place to begin with.
3.) Research the species on the net (use Google, Yahoo, or other search engines)
Be aware it could take several months learning or even a year before you may be ready to get a shark.
BTW- you never want to impulse buy a shark or shark egg. And you never want to follow the sole advice of a LFS salesperson.
