What the heck is this?

My boyfriend noticed these in the tank a few weeks ago but this is the first time we were able to catch some. They usually hide out in the sand. What the heck are they? I’ve looked through some critter ID posts but so far haven’t found anything that looks like them.

Yay. I think they're cool looking so I was hoping they weren't bad.
