Flatworm ID help

[Rainer W]

Hi, after several years of reefing it looks like i have somehow introduced some flatworms into my tank and would appreciate help in identifying these and whether they are harmful or if i can just let them get to a balanced population and not worry. I really don't want to add chemicals if i don't have to. Siphoned out a bunch a few minutes ago. Size ranges from less than 2mm to about 6mm (1/4") and color ranges from pale bownish-red to grayish-clear.

Pic very fuzzy but may be planaria.
Using a 3/8 or 1/4” tube, siphon up as many as you can
The following wrasse will eat them: yellow coris, 6 lined, lunare and melanurus
Siphon 2x a day if possible
Last option is salifert flatworm exit
If you use this, siphon dead ones daily which can release toxins

Thanks for the quick reply. I'll try to get a clearer photo this evening. I have a 6 line wrasse but haven't seen him pick at any of these flatworms. I would love to get a melanurus wrasse but I'd want to relocate the 6-line temporarily till the melanurus settles in and then reintroduce the 6- line. It's a faiely small tank (RS250) so i need to be careful.
