Starfish, sponges, tube anemone

[ShadowWolfBloodMoonBorn]

I was wondering if anyone can tell me what kind of sponges these are when I look up info all I get is pineapple sponges except for a picture or two without any information they aren’t shaped right for pineapples. Also these starfish I’m thinking Asterina but are they the coral safe kind? Also I recently acquired this feather duster/tube anemone a couple days ago but it seems to be losing some of its coloration can anyone tell me why?

Looks like ordinary sponge. There are too many species, making visual aid nearly impossible.

I can’t open the video but most asterina is reed safe, the beat way to know what kind you got will unfortunately have to be trial and error And see if it bothers any corals.

what are you feeding your anemone? Does it get enough light?

I have Fiji live rock that I have had for close to 9 years I think that have a few of those on them. Don't know what they are, but they are harmless.
