Well I hate to say it TheSamm but you are definately in the minority in thinking it can be done. Anemones need stable and quality water just as much as they need light. Now think about it. In a twelve gallon tank after rocks, sand, and equipment is in the tank, you have maybe 8 gallons of water if that. It is very hard to provide the water quality and stability in that size tank. It is best left out of any nanocube.
