Besides, most anemones are collected from the wild and many are difficult to keep. Their cells don't die in nature. They live forever in the wild and death in the home aquarium is usually due to inadequate husbandry.
BTAs are better "beginner anemones" because they often reproduce in captivity and are more lenient about their environment but even these need care requirements similar to sps corals. Tank needs to be mature (most people wait at least a year) and maintaining calcium, alkalinity, and magnesium in addition to good lighting and filtration are all needed. Otherwise they may just just keep dying on you. Check out the anemone threads here if you're still thinking about a "clown anemone."
However, if you haven't been in the hobby that long or have yet to maintain other types of corals I would personally wait until I had more experience under my belt. Start off with softies, then lps, sps, and finally anemones.
Anemone success, unfortunately, is not measured in months. More like years.
