Tried, not failed yet, but could be better.
Thoughts and observations:
- think about what coral do you want (or what are available or affordable) - gorgonians, chilis, sun corals (we leave out the scleros and dendros for now, my systems are not good for them),
- amount of feeding required, type of the food: I'm giving more, but Jens Kallmeyer feeds 3x daily, details are
here . Frozen unwashed food, especially usual homemade blend tend to foul water more, then dry food.
- Filtration and skimming should be able to remove excess and keep water more or less clean. I'm keeping filtration off during feeding, most other keepers - not.
- No sand bed - will be polluted quickly, bare bottom.
- Flow - the shape of tank is important:
the best from mine was 5g hexagon with power filter, but without skimming...
next was 6g nano cube, with side laminar flow, gire tank should work too, or cylindrical with laminar side flow.
rectangular tanks were not good, the mutual positioning of the corals and powerheads is a constant headache.
- moving LR and biomedia to the dark sump helped with bristle worms control and cleaner rock.
Photos of my tanks are
here.
You can find more information from other keepers either by coral name, tank, feeding, forums or the same, but deep water or non-photosynthetic tank (obvious

).
Other keepers are:
-
Dendronephtya study group at RC - big tanks, dedicated, not a common nano-reef level.
-
Danny Dame's tank, Holland.

At the bottom of Danny Dame page are links to other keepers presentations, pdf, especially Daniela's sun corals.
There is a lot of detailed information on the web, only all is scattered.
Good luck!
