are these bad ??

[NewFishy]

I'm just nervous I have more bad things in my tank I might need to take care of.....and I have like a bunch of baby snails I have four snails I bought almost a year ago and little snails just keep seeming to be poping up.

I never knew what the pink thing might be..

and I have no idea what that spiral looking thing is.. but it looks like legs or something are stickin out every now and then

1 an 5 look like brittle stars, harmless
4 could be a small feather duster? If so also harmless.

In the fourth picture I don't know what that circle thing is..

Ya feather dusters live in tubes, so im guessing thats wht it is..... The thing that comes out, does it kinda look like a flower?

 

[NewFishy]

No Its not that..I have lots of feather dusters. That round thing wasn't there before..and it kind of looks at times like a snail would...but it doesn't seem to have moved or anything

In pic 4 the round thing appears to be the operculum of a deceased snail

I don't see anything bad in any of those pictures.
