[ELI5] How do deep-sea fish get displayed for public view with lack of pressure?

If something, say an angler fish or a chinese spider crab, were suddenly hauled to the surface and captured-- wouldn't they die from the sudden lack of pressure? Like an astronaut with no space suit? How do public aquariums display the creatures of the deep? (Like, the DEEP-deep of the sea) Are their tanks pressurized?

Good question! Actually, deep-sea fish's eyes burst when they get taken up to the surface (but that can also happen with regular food-fish). Blobfish also don't look like that floppy pile of meat when they're in their natural habitat, they are kept neat and round by the high water pressure. Also: cells are pretty magic so they can withstand huge pressure differences which means the fish will not completely burst when you take it up.
