I would also imagine the ease of care would depend on the size that you get your aro at. I've never had an aro smaller than about 5 inches so I can only go off of what I've seen/read, but it seems like the really small ones are delicate and the success rate isn't very high for most fishkeepers. I believe most would recommend a 6-7 inch aro or larger to start with for new aro owners. Just my 2 cents though.
