Identify flat worm/nudi and what to expect.

Looking to identify this flat worm/nudi..

Does anyone know what it is?

I took it of the front glass. Have not seen it before.

polyclad flatworm, These are a nuisance and one of the harder ones to erradicate as they hide in the tiniest holes. Typical removal is via siphoning with 3/8 - 1/4" tubing.
Velvet nudibranch will eat them and so will wrasses such as : Yellow coris, 6 lined , lunare and melanurus especially if there are many of them.
You also have to inspect daily for 2 weeks for the presence of eggs which are tiny and will quickly increase the flatworm population.
Last resort is chemical removal with salifert Flatworm exit which MAY work. It is important to siphon the dead ones as they can release toxins .

Critter Identification: Leopard Polyclad Flatworms – First Time Fish Keeper

Flatworms come in a range of colours, species, threat levels, swimming varieties, and some can look so exotic that you may secretly wish for an infestation. The Leopard Polyclad Flatworm, is not a species you would wish for in your aquarium.

Don't know where it came from.. nothing new inside the tank that hasnt been dipped.

The link says special diet: clams and snails.. I dont have any of either.

I do have small snails that came with rocks or early corals but nothing else.

I have also only seen one.

Likely in a hole in one of your rocks. It will eat coral slime and other things

Info on net says it's not likely to multiple like ordinary flatworms since they get big.

Time will tell..

Now I know what it is.
