Thanks for the advice! I did not consider a hiding space but it makes sense. I've heard how sharks can be anxious. For a fully grown 6 ft reef shark, how big do you think that a cave should be?You must consider environmental needs such as tank setup. Very fine sand as it will get scratched or injured from sharp sand or crushed coral.
With that, you must consider tank mates if any. There are some fish and creatures the shark just won't go after. It will almost NEVER go after stingrays, damsels, NEVER corals, etc. but corals and rock can have sharp edges- Another caution.
If the tank mate you want always will get eaten, no matter what size it is (eg blue tang or wrasse), You NEED to give it hiding spaces such as Rocks, corals, sand and caves to hide from the shark and they'll be safe but again caution on sharp rocks.
You need to stay on top of nitrogen in tank and Tank size . . . . . You can't keep a 2 foot shark in a 6 foot tank. Even a 3 foot shark when it reaches that size will need something along the lines of a 12 foot round tank at 6 feet deep to meet its' swimming behavior.
Also, I think you might have missed the context of this thread. I'm designing an outdoor pond, as of right now, I've been suggested a minimum of 32,000 gallons (30 feet diameter by 6 feet deep) to 113,000 gallons (40 ft by 12-foot). What's your recommended size for keeping blacktip reef sharks till maturity?
