Tomato clown hosts RBTA

I purchased two Rose Bubble Tip Anemine (RBTA in hobbyist term) from a fellow hobbyist. The disks were approximately 4″ in diameter when fully inflated. At this time I have a pair of percula clowns and a mature tomato clown who has not hosted and anemone for over two years. Within 10 minites on the anemone’s introduction, the tomato is already making herself comy in it. The percs? Not even interested
