Just because yours did ok in a new tank doesn't mean it's common. The waiting period also allows a newbie to learn and get accustomed to maintaining the tank.
To answer the question, a BTA may be a good choice if you haven't got lots of room since Occelaris' naturally host bigger anemones. It may take a while for them to host though, mine needed like 2 months.
Before you get one though make sure you've got good lighting, i.e. T5 or MH and an established tank.
