The link takes us to a video of an Australian Lungfish. You buy them from a guy in Queensland and they cost a lot. They are pretty boring and hide during the day. At night they come out and eat anything that fits in their mouth.
the link is about the Steinhardt Aquarium in San Francisco, California, US. It’s incredible. I visited many times as a kid & loved the place. At 92, that fish is the oldest aquarium fish in the world. Not sure why the link isn’t working for you. Sorry. I tested it when it was posted and again, right now. It is from CNN.
