We have a Condylactis and Bubble tip anemone. The condy was opaque white with purple tips when we got it. It is now brown and doesn't seem to react to our touch any more - but still eats. The bubble tip was bright green and is now turning a murky brown color. It shrivels up about 50% of the time. But when it is extended it doesnt look very impressive. It's been eating as well. We have appropriate lighting. We feed them shrimp once a week and supplement the water with phytoplankton and biozyme, and have just begun supplementing with iodine and calcium on Sunday. Our water quality is excellent. What could be going on?
