Deformed duncan tentacles?

My duncan has developed weird, deformed tentacles in the past month or so. I've had it for about 7 months, and it's grown beautifully from one head to about 9.

 

So are these creepy tentacles a sign of a problem? What could be the cause? Too much flow? I didn't think the nearby sun corals could sting but could they be irritating it? It's only the oldest, original head that has started getting the weird tentacles.

One tentacle even seems to have a strange whitish growth on it. Is this some kind of mesenterial filament? A pest? I don't think it's moved much since I spotted it a couple days ago. When I poke the area it kind of condenses/retracts with the tentacle.

There is a mushroom on one side that has started to bother a different head, but it is reacting differently, just keeping the tentacles retracted with the tips looking somewhat "burned."

What's going on with my poor, ugly duncan?

As duncans get bigger, their tentacles also grow and get longer and gnarlier. If you look around here, other forums, and google images of really mature duncan colonies, a lot of them look more reminiscent of an anemone than duncan frags or small colonies.

 

Edited to Add: Here is a picture of a really large, mature colony with super long tentacles from Reef Central
