Indeed, you won't find many with much experience, they're fairly new to domestication, requiring care with the flow as they get tangled easily in currents, hence the specialist tanks that tend to be on the expensive side.
They're actually quite cheap to keep if you compare a good sized tank against a large display reef for commercial sites, but must of us have steered away as the set ups tend to cost as much as a full reef to start.
Prices are coming down though, so it may be an interesting next step for the hobby.
