Hitchhiker ID please

Part 2 of Tampa Bay Saltwater @LiverockRocks came in today loaded with hitchhikers, critters, and freebies!
Please help with the following

The top critter is either a spaghetti worm or hair worm - it's harmless/beneficial (so a keeper):

Looks like either a hair worm (Cirratulidae) or a spaghetti worm (Terebellide) to me - if the tentacles all come out from a single point, it’s a spaghetti worm; if they come out from basically all over the body it’s a hair worm.

I can't see the worm directly below the spaghetti/hair worm very well on my phone, so I'll try to take a look at it (and any others I don't ID right now) tomorrow.

The bottom left of the same pic shows a flatworm that you don't want in your tank.

On the right, there's some kind of shrimp (possibly a pistol shrimp missing the "pincers" of its claw?) and what appears to be a keyhole limpet of of some variety.

I'll take a closer look at this bristleworm when I have time, but it's likely harmless/beneficial.

I'll take a closer look at the crab and pink blob, but the brittle starfish is fine to add.

Again, add the brittle star - the shrimp and keyhole limpet I'd say add with caution, but odds are in favor of them being safe; some pistol shrimp may be aggressive, though, and a small number of keyhole limpet species are known to eat SPS.

Again, I'll take a closer look, but the crab above seems like it may be a ruby mithrax crab or relative (which are about as reef-safe as true crabs get).

The above are porcelain crabs - totally safe and neat (porcelain crabs have three pairs of walking lega, two large claws, and a pair of "windshield wiper" legs under their body; true crabs have four pairs of walking legs, two claws, and no "windshield wipers").

These two are probably not keepers - black-tipped claws are usually a no-go with crabs.

Alright, I'm a few days late on this (sorry) but here goes:

I'll take a closer look at this bristleworm when I have time, but it's likely harmless/beneficial.

I'd guess (but may well be wrong) that this is a Hesionid worm - most likely harmless/beneficial.

I'll take a closer look at the crab

The pic's a bit too blurry for me to feel confident in giving a specific ID, but I feel pretty confident it's a Pagurid species (taxonomic family Paguridae) of hermit crab. If I had to take a guess, maybe Pagurus criniticornis (hard to find good pics of this one though)?

Regardless, it'll probably stay small, and it's likely about as reef-safe as the average hermit crab. Did it have a shell when you found it? Have you offered it any shells?

and pink blob,

Any chance you could get pics of this from some other angles?

If not, my first thought would be a fleshy limpet of some variety - this would have a shell hidden in the center, and it would likely be good CUC.

Again, I'll take a closer look, but the crab above seems like it may be a ruby mithrax crab or relative (which are about as reef-safe as true crabs get).

I don't think this one's a ruby mithrax, but I would guess it's a Mithracid crab of some variety, so most likely relatively reef-safe (though, much like emerald crabs, they may potentially cause issues as adults).

Thanks so very much for your support. This rock is so full of life. Spotted two mantis shrimp. Three wild anemone. So much coral, sponge and tunicates. Hopefully some will stay healthy and alive.
The crabs were all released in the tank and Refugium. For better or worse.
The pink blob looked like a snail or limpet with a clear shell. Both rose colored.
Attached is the mantis and wild anemone

Nice - looks like a lightbulb nem (Bellactis lux), so it shouldn't be bad.
