Flatworms good or bad?

[william_acker]

So I have recently seen flatworms in my fuge. None in DT but I'm sure they're in there somewhere. My question is are they bad? They are the whitish clear ones. I've read that they are reef safe but wanted to know anyone's experience with them. And how they handle it.

Thanks!

They only become bad when their numbers are so high that they blanket corals and block light, thus killing corals. (Unless they are acro or other coral eating FWs, those are very bad)

I always liked them because I felt that they were just more diversity in the tank and that they were also free food for many fish. Wrasses, clowns, mandarins and many other fish eat them.

Most people hate them.

I feel the same if they help eat detritus and feed some fish then petty cool. But as long as they don't harm the corals I could care less.
