Red furry hitchhiker

[Fishbird]

Hi again, sorry, I know these pictures are not the greatest but they’re the best I’ve been able to get so far. Is there any chance that the bright red is a sponge being encrusted by zoas? KP aquatics sells a red ball sponge encrusted with Parazoanthus swiftii so I’m wondering if that’s what this is. The things that might be polyps are 1/8” to 1/4” if I had to guess.
Thanks!

Hard to tell. Crab?

There are definitely multiple round things with tentacles. I guess my main question is whether they are zoas, sponge tentacles, some other kind of coral, or some kind of tube worm. I have to click on the photo to enlarge it and then I can zoom in. I’m hoping that works for others. It’s definitely not a crab though I wish I had found a porcelain crab!
