Not sure what's BS about saying they can be tough to keep and need more light and space than 30W over a 10g tank - couldn't be more specific since the OP didn't state what type of anemone they wanted to keep, just a general question of 'are they tough to keep?'. I'm new to SW, and if I'm wrong about something, by all means correct me, but as blueiz25 said, the tone wasn't really required.
