Of course a 30g will be easier. That wasn't the poster's question, though. I'm sure he understands the difference as he wouldn't be asking if it is true that nanos are so difficult if he didn't.
As for price, I have seen both nanos and 30g+ setup and (depending on what you are setting it up for) a 30g is much more expensive. From what I understand, this poster wants a low maintenance tank. A 6g eclipse with the biowheel taken out and the bulb changed is rather low maintenace (topping off with fresh water and doing water changes on such a small tank is very easy.). It also costs less than $100 to set it up and get the live rock.
As for corals for a tank like this, I would suggest a Bullseye Mushroom Coral or Hairy Mushroom Coral. You could also probably get away with some of the colony corals but you would want to house them alone as they can take over an entire tank. |
