This thing appeared out of nowhere today

[AndyinAtlanta]

So I checked my tank in the morning and everything looked just like it always does, but when I come home I find this on the glass:

Anyone know what this is? It has moved a tiny bit since I took the photo (top half is bending more). I figured from the front that it's a snail, but from the side it's very thin (as thin as a piece of paper). It's about 1 inch long for scale.

Looks like a flatworm (Platyhelminthes)

flatworm; do you have torches, hammers, frogspawn?

 

[Gernader]

It looks like an euphyllia eating flatworm

 

[ReadySet-Flow]

flatworm, nuke it from space.

Yes, yes, and yes.

Oh wow, thanks for the quick response. I grabbed it immediately and tossed it. Anything I need to look out for moving forward?

Done and done, snatched it out of the tank.

the flatworms will live near the skeleton and the meaty flesh on your euphyllia and will be hard to see. you could try to pull out each one and dip them and see if anything starts to wiggle? depending how many you find and how big your tank is, follow on steps can vary.

I bought a torch from local place and dipped it when i got home. sure enough, it had a flat worm. about two months later i noticed something on the meaty part and sure enough it was another flat worm (I added no other corals during that time). I spot dipped my other corals every couple months in a cycle and knock on wood, almost eight months no flat worms found.

What would you do if you can't easily dip your euphyllia's? They are all attached to the rocks. Its the first time I've seen one of these worms, should I assume there are more? Is there a preventative way to treat the tank? Thanks.

Some people get wrasses that will eat flatworms, others will try to manually remove and use flatworm exit as a last resort, but with some flatworms when they die they leave a toxin in the water, not sure about this specific flatworm though.

Only way to be sure!

We have a Space Force now - we can do this! Coordinates?

preventive; quarinte and dip everything going in and types of wrasses.
Now that you have worms; wrasses and maybe flatworm exit. There allot of videos on flatworm exit, toxins, having water change on stand by, carbon, etc.

Polyclad flatworm.
