Upside down jellyfish stings?

[justinl]

a couple of corrections/additions I feel I need to make:

- upwards flow isn't really necessary. just low flow.

- they rely mostly on photosynthesis so lighting has to be bright; food doesn't have to be daily though they will eat it and would probably enjoy daily feeding.

-sandbed depth is irrelevant. just has to be oolitic (fine grained). don't feed brine shrimp.

-sandbed must be extensive. these can be kept in standard aquariums if you plan it right. you don't need a kreisel because they are benthic.
