Well, whether or not this tank would have remained healthy as an eight gallon is unknown, because it is now a 30 gallon. Oops!

However I recently set up at 16 (10 gallon footprint) and it has been going very well. I've noticed that while one tank will support certain corals, others may not. For example, my 28 gallon, I can't keep mushrooms in it. But in my 16 gallons, into which I moved all my shrooms, they are thriving.

The Royal Gramma was a WONDERFUL addition to my tank. However, when I got a few other fish (a goby and some false percula clowns), I noticed that he became much more reclusive, so I'd recommend that unless the only other fish are gentle gobies / blennies (ie scooter blenny, randall's goby - as opposed to a watchman goby or something), that the RG be the only fish.

Anyway, I still feel that properly taken care of, a nano is fine and easy enough to keep. Can't slack, though, because it can go downhill fast.

On more than one occasion, I was late by (at most) a day for my water change, I noticed a marked decline in all the corals... IE they were all closed, slouched looking. And perked up as soon as the change was done. I still notice that in my 30 gallon, but less drastic of course.
