BTA is a stinger...

A host anemone will have a strong sting and generally they'll "win" any confrontations. Hopefully they'll settle down for you. Sometimes, anemones move when they are unhappy and as well, sometimes they split when unhappy. Have you had any changes in your tank specs over the last while?

Oh and Bob, you git a gold starr four you're speling prouwess.
