Critter ID please

Hello fellow reefers

I just got a coral delivery and found a few hitchhikers. Can someone give me an ID and let me know if they’re friend or for? Thanks

They look like flatworms. I can't tell you what type (possibly EEFW if you got euphyllia), but I'm 99% sure you won't want them in your tank.

There are plenty of flatworms that aren't really a problem, but yeah, I can't think of one that people consider good and there are harmful ones.

I hope you dipped those corals!
