A white purple tipped BTA please post a pic that must be awsome to look at!! As for food I feed mine a variety of foods frozen mysis shrimp,and meaty medely, krill,and sometimes I find if an anemone is being fussy they will take flake food I use ocean nutrition prime reef. They say you can soak the food in vitamins,garlic, etc. but I find when I do that the anemone pull away from it I think although it's good for them it's like giving a kid medicine! so I keep it plain but always float the food in a container with some tank water in it so its a good temp and more natural for the anemone!! GOOD LUCK I love my anemones my BTA is probally my favorite in my tank right now!!!
