Open Brain coral super inflated in the middle

[Zwinger]

Hi fellow reefers i was wondering if someone could help me with some answer with whats happening with my open brain coral. The last couple weeks it seems to only inflate in the middle portion/mouth of the coral rather then the edges, I feed this coral twice a week and it has no problem accepting food. When I google and research other brain corals I don't see any inflated quite like mine. Is mine unique or is there something Im doing wrong thanks.

Looks good tbh, maybe try laying off the snacks for a bit? No idea honestly, curious to see what people think

They do this sometimes to move(inflate to be picked up by the current). Plate corals do this also.
Looks to be quite happy to me.

Sometimes they are just odd shaped. I bought a trachy a while ago that had a barnacle right where the skeleton folds. The barnacle died, but it caused it to split into 2 separate heads on one skeleton. They do not look like a trachy head now as they are perfect circles(almost lobo ish), but it was certainly a trachy when i bought it oh so many years ago.

If it was closed up, and I could get a pic of the skeleton, you could see it is most certainly a trachy.
