Should I add these hitch hickers to refugium or DT?

[Crash]

These buggars were hitchhiking on some macro algae I bought. Along with a baby brittle seastar and a serpent seastar. I heard these guys can be good because they eat detrius and end up being food for other fishies.

If I believed everything I read on the internet I wouldn't be here lol. So anyone have any advice/experience in dealing with worms? If I do add it, does it go in the DT or refugium to make the biggest difference (would perfer not to go in the DT because they are just nasty to look at)?

Most likely you already have them in your tank. Even if you don't they are a good part of a cuc just don't touch them cause their bristles will stick in you like fiberglass.

In that case, I will add him to the refuge because the cuc there consists of a lonely nass snail. Thanks much!
