I'm not that familiar with the nano tanks, but the site that Pat mentioned in that other thread (nanotuners.com) has some good plug-n-play option, it seems. One issue with lots of light on these nano tanks is the amount of heat that gets trapped... tends to heat up the tank a lot. If you really really want an anemone, then upgrading the lighting is really the only thing to do. But just be aware that this might not be the last upgrade in order to keep an anemone. A chiller might be your next move, in order to keep the tank cool. You might want to check around and see if others have had to go this route when they upgrade.
