What the heck is this?

[Spark326]

There are several crawling on my glass and eating pods.
It eats from the rounded end and kind of slithers.
Anyone know what it is and if i should be worried??

Flatworm.

If you have any airline tubing handy you might want to start removing them one by one.

Like a parasite?!

I'd say flatworm also, but I'll let you be the judge. Here is a hitchhiker guide. If it has a small hard shell on its back you are good. Otherwise, it might depend on what your coral stock list is like.

Acoel flatworm. Not harmful to coral but can be a nuisance in numbers. Siphon it out if you can. Lunare or melanurus wrasse will eat it as will a blue velvet nudibranch
