Flatworm ID

[Wet Sleeve]

Quite sure these little fellas came on some recent frags, don’t seem to be bothering much aside from me.

curious if anybody can ID them, they’re extremely small, maybe 2mm and brown in appearance, I’m treating with PraziPro atm after seeing it irritates them in a coral bath, however they’re still swirling around after 45 minutes in a concentrate, which I suppose is normal as Prazi claims not to be more effective with concentrated dosage, was more to see if they’d react.

I religiously dip every new addition in iodine bath but that has no effect on these guys.

Have you tried coral rx on them? I take the battlebox approach to dipping what will it take to kill ALL the pests I find and if I can't kill them they sadly don't go in the tank.

Usually I am pretty good at spotting them but these guys are tiny!
I just moved to iodine bath because I had mixed results with Revive, I’ve tried coralRx in the passed, may start keeping it on hand again.

Red Planaria would be my assumption, cant really see with the blue light on it.

Here’s a video of them irritated in a PraziPro bath, they don’t resemble red planarian imo, more brown in appearance and very small.

however hopefully the video helps find this critter ID!

Here’s a better photo without so much blue.

The ones I had looked like that, those just seem small.

Yeah, the size of them is throwing me off.

appreciate your input, hopefully the PraziPro works it’s magic over the course of a week, if it doesn’t eradicate them completely I’ll have to try Flatworm Exit as PraziPro is banned in Canada now.

I’ll have to work on getting a back up bottle sent from the states.

Acoel flatworm.

Acoel flatworm.

Good/bad? I have the same and can’t figure out if they are benign enough to leave alone

More of a Nuisance then anything, they don’t physically harm any corals.
I’ve done multiple flatworm exit treatments at this point and am still finding the odd ones.
I’ve also added a coris wrasse to help keep them in check.
