thing

Hey guys so i noticed one of my hermits has something growing on his side inside his shell it usually hides but i got it to come this took some pictures i was thinking it’s some type of feather duster maybe? If so i kind want to keep it how to extract it lol or will it come out on its own

Hi. These recently appeared in my sump. They’ve been stationary but I cannot figure out what they are for the life of me. They’re a clear/whitish color. Any ideas?

Noticed these white things while doing a water change today. Anyone know what they are?
