[Notsolostfish]

Can someone please tell me what type of flatworm is this? I knocked down my torch while glueing it, and found this. Is this flatworm!l?

Yes. While they are not harmful as red planaria, they in numbers can smother bases of coral and block the needed light for production of zooxanthellae which is their energy source.
Removal can be accomplished by siphoning them with a 3/8" tubing into a nylon stocking and discard
OR
Add a wrasse such as Yellow coris, 6 line, lunare or malanurus OR even a springieri damsel which will eat them

With the number you have, for the next 2 weeks you will have to look for eggs and scrape off as there is likely some and would be future acoels. Eggs are really tiny

Definitely a flatworm, I have a 6 line wrasse and never see flatworms, despite adding probably 60 corals over the last 6 weeks or so. Either I am lucky with where I get my corals from, or the 6 line does its job :)

I love my 3 sixlines (different tanks) for the same reason.

unfortunately Yes,

get a six line asap if you don't have one already,
