I highly recommend you remove that Saddle back clownfish, A. polymnus, from your Haddoni. My experiences with A. polymnus was horrible. They naturally use Haddoni as their host but extremely aggressive and detrimental to the anemone. They often dig into the mouth and go INTO the anemone entirely. While inside the anemone they would rip and eat some of the inner tissue of the anemone.
I love natural symbiotic relationship between anemone and clownfish so I set up a tank for my Haddoni and A. polymnus. My Polymnus pair killed two Haddoni, and was in the process of killing my Blue Haddoni before I wise up and remove them. Now you only find Polymus in my tank over my dead body. Do a search on Polymus if you don't believe me. Happens a lot. Their favorite sleeping place is inside the anemone.
Good luck. Please don't let me tell you: "I told you so"
