So I was wondering if anyone has ever kept an upside down jellyfish, they look pretty cool and I'm considering of getting one since I have a nice refugium setup with a mangrove area. I know cardinals in general like to hang out in mangroves but I also wanted to add these jellyfish since from what I've read they're found in similar areas? Any thoughts or ideas and experiences to share? Also if anyone knows any other type of animals that would do well in a setup like this please let me know. Thanks in advance, Fortunato
