This is how my anemone has looked for four days now!! its been eating all the levels are great. The tentacles have been inflating than deflating. The mouth has been elongated for the entire four days.
Unfortunately I'd say it is dying. I have a few anemone's look like that and last for quite some time. But the outcome were all the same. My rainbow anemone is doing Great but the other RBTA's in there died….who knows why.
I would definitely not feed an anemone daily. A small amount of food once per week or twice at the most is more than enough to sustain an anemone. Overfeeding could have caused its demise
