A few worms/flukes ?? On glass

[mrnicebug]

I have no clue. I just treated (twice) for flatworms using flatworm exit. This is long and moves fast. Doesn’t have the shape of the brown flatworms I eliminated

Can you see eyespots?
This isn't a fluke, as adult parasitic flukes cannot live off of the fish host.

Well, given the fast movement and a pair of eyes, I would say that these are non-parasitic turbellarians (Planarians). I can't rule out though, that they are not micro-predators against corals and such.
