Hello from oahu, it is actually illegal on the islands to collect, buy, sell, and ship corals, natural live rock, live inverts, and live copepods to Hawaii. And starting in the new year it will be illegal to catch, buy, or sell native hawaiian fish and any fish surrounding the islands. Because of this we are limited to FOWLR systems, and fish prices are going to rise on the islands. The live rock has to start dry or be aquacultured by a licensed person its mainly from molokai. You can not take any natural live rock from the ocean. It makes marine tanks difficult but not impossible, I have a 75 gallon tank with multiple Hawaii native fish from before the ban as well as a mandarin goby, blue spot goby, scooter blenny, 2 pairs of clowns and a flame angel. all my live rock started as dry rock its important to read and know the laws for the islands before starting because people will ship things here and some people get away with it, others are confiscated and people fined during random checks.
