Going to Hawaii - can I bring back fish?

you can bring fish and inverts back with you with proper documentation, invoice species list, prices, for customs clearance and taxes. you cant bring back any liverock, clams, corals, or cities controlled livestock without a cities permit. any livestock would need to be packed in styro with heat packs and oxygen for a reg 48hour journey. not a carry on trip. it would be cheaper to buy locally
