Anemone not eating

[Conway23]

Can anybody give me some tips on my sebae anemone. Had it for about 2 months and it was always slow at eating, to the point that food would be taken off it before it could be eaten. Over the 2 or so months it's tentacles have been getting smaller. I've tried isolated feeding so nothing could take it's food but food I put near it's mouth is still there an hour later. It's still in good shape though, not wasting or anything like that, just stumpy tentacles and not taking food.

Do you dose Iodine? If not you may want to try that.

I've never fed my anemones, they seem to do great.

My pink tip ones doing fine. Only difference is the clowns host the one that's not doing great
