Weird type of planaria/flatworm? Help!

[saltt]

So in the past week i've noticed these little guys on my glass and live rock. I really can't find anything describing what they are, they don't seem to be eating any coral or anything like that, all my coral looks fine. They don't have a red dot on one end like i've read about harmful flatworms, and they have two little tail spikes at their butts. Does anybody know what the heck these are?? I really don't want to use flatworm exit, so if they aren't harming anything i'd rather just let them run their course i guess..i just wanna know what they could be.

Thanks so much. Whats weird is that they are staying pretty small. in the pic of the websites they look huge and mine are still tiny after a week. Also it doesn't seem like they're getting out of hand (yet) *knock on wood* soo i guess that's a good thing?

I don't know how big your tank is, but I have a Melanurus wrasse, never even seen a flatworm. They're nicely colored and peaceful as well so you might look into it depending on your tank size.

A lot of people including myself. Have found these guys on our glass. They aren't the harmful flatworms, eating only algae.

Thanks guys! They seem to be eating algae, and I have a small yellow candy hogfish who nips at the rocks occasionally, not sure if he's eating them or if he's eating pods. I also have a mystery wrasse but I think he's too big to notice them since they're so tiny. My tank is a 28 gal. nano cube so a Melanurus isn't really appropriate. If anyone else has had experience with these please say so!
