Splitting isnt always a sign of good health, it can be an indication of stress, thats why you hear people say that their anemone split following a move, new tank settup, etc. etc... If your anemone was splitting once a month, theres a possibilty it was reacting in survival mode due to some source of irritation. T-5's in my opinion would be a much better alternative than Pc's. Pc's usable life span is about 4 months and are expensive to replace. Ed, does your BTA have the bubble tips under the T-5's? It also depends on the origin of the specific species, some come from deeper waters, some shallower, blah blah blah.
