Well if you search this forum there are hundreds.of threads on them, usually a couple per page.. They are the most common anemone kept. Also the anemone faq that is stickied at the top of this forum..
Bta's are one of the most hardy and one of the easier to keep anemones. They also can live in a greater range of lighting conditions too.. They should be fed once or twice a week. I like to feed small chunks of silver sides or krill. Some people have had successes feeding them with other stuff like shrimp, clams, fish, squid etc.
