Yeah, If you look in the first post he has a quote
"THEY are called echizen kurage and they sound like monsters from the trashier reaches of Japanese science fiction.
They are 6ft wide and weigh 450lb (200kg), with countless poisonous tentacles, they have drifted across the void to terrorise the people of Japan. Vast armadas of the slimy horrors have cut off the countrys food supply. As soon as one is killed more appear to take its place."
we get blue jellyfish in at our lfs and they go for $15.00. you need an aquarium with no edges or live rock because they bruise easily and die. cool lookin tho.
