I found this interesting little video on the great youtube. What I find most interesting about the video though is how long he managed to keep them alive for. According the the YouTuber he caught these squids on the North Shore of Oahu. He managed to keep them alive in that tank for several weeks where he feed them feeder shrimp and according to him they only died when he tried to feed them fish. I find this interesting seeing how he managed to keep the little buggers alive for a long time in that tank (small and non circular). And guessing from the setup it was probably home aquarium too. His comments made on regards to his video Spoiler "thanks guys, these squidz were caught out on the North Shore of Oahu." Untagged reply a youtuber "if you are on Oahu & u want to buy one I have one. send me a message or whatever. i dont really do YouTUBE much." "these were actually pretty hardy. they lasted the ride home without an airpump. and lasted a few weeks while on a diet of saltwater feeder shrimp...but the second i tried feeding them saltwater feeder fish ...they died."
