Sand sifting starfish concern

[JairCaballero]

Heres my sand sifting starfish since ive had over 3 months, its been doing so well it was very active but for the past week or 2 its been just chilling in one spot and not as active. i also noticed its been a color change on its bottom from khaki to pink/purplish. all of my corals clams and other invertebrates seem to be doing just fine but his movement does concern me. i can see it is still alive due to its polyps reaching out but seems a bit weak.. anysupport feedback is greatly appreciated!

Still don’t see it

Seems like it loaded.

How old is the tank?

Without sufficient microfauna, starfish often starve, even these sand shifting ones

taking it out of water will only make it worse
