Well if I wanted to build a tank that big it would go well into the ten thousands, its an indoor pool, 10 meters by 10 meters and 4 meters deep at all parts (already cycled to remove chlorine and renovated to work as a pond) I am going to add live sand at about 30 centimeters deep at all points and turn almost all of it into a reef tank with certain corners that are just sand. The parts that will have reef corals will be on a hill that is made of sand so it will stick higher, there will be lots of live rock and the sand is aquarium sand (not just any random ones).
I am trying to create an ecosystem situation where I will only feed the shark.
1. I just want to know are all the fish in this list able to out swim sharks or be too big to be eaten by them? If not, tell me which ones please.
2. And also can all the fish in the list survive in an ecosystem situation with only the fish/plants of that list? If not, what fish needs what to survive?
3. And another question, can I just empty all the plankton into the main tank and let them breed there or do I have to keep adding new plankton that have been bred outside of the tank (same question for Brine Shrimp)?
4. If Whitetip Reef Shark are harmful what other Shark can you keep (which looks like the common shark) that is completely harmless to humans?

well i think i see a few fundamental flaws in your stock. one being that in the long run eventually i think those occelaris clowns and mandarins will probably get caught and eaten by some much larger preds and thus i would avoid adding them.
also while i don't know much about sponges i'm pretty sure they are a favorite food of angels and thus may be depleted quite quickly as well
i see the shrimp (brine/glass) in your cleanup crew being ate up very quickly so i wouldn't really waste the time with them unless you intend on supplying them as food for the others. i don't think they'd last long to do much cleaning except for the cleaner shrimps who the fish might let be.
and even with that large of an ecosystem and such i think in the long run you're still going to have to feed foods for all the fish rather than just the shark to help prevent turf wars breaking out over food and to keep the predators from hunting their tankmates
finally, good luck. i know i'm surely not dareing (or rich) enough to try something like this as all out chaos could end up breaking out or it could work out beautifully. if you're actually going to go through with this i would get into contact with some zoo's for tips rather than relying on forum information
