I don't even know where to begin with this hitchhiker ID

[Ptyochromis]

I was looking in my fuge when I saw something in my chaeto. Long and thin, maybe 1/4-1/3" long and no wider than a strand of chato. At first I thought it was a nem, but it started to "inch" along like an inchworm; using the top of its body to pull itself along. It would stop, stand up straight and move about in the current.

Uppon closer inspection I noticed it has "arms" with hooks on the end that look a lot loke a praying mantis. It has roughly 4-6 body segments. Near the middle of the body it looks like it has extremities resembling the swimming legs of shrimp, but much more spread out. It also has antennae that are about .5-1x as long as the body.

I have no idea what I have. It is presumably predatory, but I would really like to know what I'm dealing with here.

Humm, looks like it.

They look like they could take out fish larvae. Whats the consensus on these guys? Good to keep around for fish food?

If you are not breeding fish, they will be fine. If they manage to get up into your display tank I imagine a fish would make a treat out of it.
The main reason people think they are predatory is because of their long claws or gnathopods.
I really don't think you have anything to worry about though.

They are omnivore and the praying mantis of the sea. I would try to keep it

I was watching and I saw it go to town on some bubble algae and cyano.

I'm picking up an L. swalesi tomorrow. Think it would eat these guys? I spoted 3 of them in my fuge lol.
