Good Crab? Bad Crab?

[OhTheHumanity]

I got a few crabs on my LR with long antennae, probably twice the length of their body. Good or Bad?

Also got a slug looking thing that has rows of spines running the length of the body. Any ideas so I can do a search for a picture?

Sounds like shrimp, I'm not aware of any crabs that have antennae.

Nudibranch or possibly a sea cucumber.

Porcelain crabs usually have antennae. Quite long too.

This is what I ID as a porcelain crab...

Found this on a google search, no real pic, but found those too...pretty cool, learn new stuff all the time. Still think crabs are best served boiled with melted butter and lemon
