Is it fungus? Pests? Gmk help

[GSnake]

Hi
Dunno what's going on with my gmk. It was very bright and got dull, closed up with these white hairs on it. It's still relatively new. What is it, what should I do? I got revive and reef primer dips on hand.

Thought I'd add my seduction zoa on here (last pic, the double head) as well. It has detritus or something on it.

Can you post better pictures? Please use white lights and be sure they are focused.

Thank you,
