Jellyfish: man's new best friend? It's finally possible with the Desktop Jellyfish Tank. Jellyfish can't live in a regular fish tank because they will get stuck in corners and sucked into filtration intakes.
If I ever have a pool I'm totally going to get these! The Ocean Art Light-up Jellies from Swim Ways are eerily life-sized jellyfish decorations for swimming pools. Each light-up jellyfish has LEDs inside and glow as they float across the pool.
