Future 12 gallon Nano

[Cwhite]

Hi, I am in the very early planning stages for a 12 gallon nano. I have freshwater tanks but really like the idea of a small reef tank. I'm thinking about it all now because I don't want to make any mistakes with it. I was wondering if it is possible to keep a pair of Amphiprion ocellaris as well as one other small fish. Is there enough room in a 12 gallon tank for this? If so, what fish would be ideal. Also, why is it not suggested to keep a host anemone with the clownfish?
Thank you

Anemones are delicate (need a stable mature system) and require a good bit of light. They also get quite large. All of these are major issues in a nano tank.
