Shark tank size

    This is more of a research thread. What would you guys say is the smallest acceptable tank to permanently house a shark. To be specific a Cloudy catshark, Coral catshark or Izu catshark.

    Sharks need big circular tanks. This is because they like to swim in circles and if the tank is square then the sharks will bump into them causing major damage and possibly death. I'd say (this might shock you and people may disagree) a 150 gallon circular tank. Sharks quickly out grow their tanks so this is why it is so large so you can keep them for a while.
