They do not eat in the sense that they have a mouth, so you cannot feed them. They pulse to move water over their body and then absorb nutrients from the water in this method into their body.

OK thanks

then the nutrients are absorbed by the body.
but in what form?

 

[coltrref]

It is also possible that food roids reef small as to be consumed by the method of absorption?

"Since they do not feed significantly on large solid matter/plankters, they are quite safe to keep in a (coral) food-producing refugium with little burden to the functional benefits of the vessel."

"Xeniids are also some of the most successful cnidarians in symbiosis with zooxanthellae and seem to derive the overwhelming majority of their "nutrition" from the products of photosynthesis (thriving in controlled culture systems without feeding of any solid matter)."
