Keeping jellyfish

[ScubaSteve]

Moon jellies are a tougher to get your feet wet with as they require a planktonkriessel and live baby brine up until they are roughly 2 inches when you can switch them to prepared foods like cyclopeeze. It not impossible, just takes more work and set up. I fully encourage you to go for it.

The easier ones to start with are cassiopea (upside-down) jellies. They're photosynthetic and can take a bit more abuse as they naturally occur on disgraced rather than open water, so you won't need a kreisel.
