A.) Looks to me like the beginning of CyanoBacteria mixed with detritus. Do a water change and syphon it out.
B.) Very possibly died. Not knowing how long it has been retracted for doesn't help. Usually from what I see there out most of the day everyday.

I'd personally test your water for Nitrate, Nitrite, Phosphate, PH and Salinity and report back with the results. How long has the tank been running for? From what I can see it looks young.

Yeah about a year what do u syphon out though?...also how can I keep the nitrite phosphate PH and salinity low??

Looks like the start of turf algae.
Can you give us your water parameters? Like, nitrates, ammonia, nitrites, phosphates. How old is the tank?
Your COCO Worm isn't in there.
