Flatworms n Coral QT... came in in leather coral

[User]

Hi guys

I recently got a large leather coral, and almost immediately got hit with a bacterial bloomthat took 11 days to clear. Tank cleared up to reveal hundreds of small flatworms on the glass. This was almost 10 days ago

no acro in the tank, so assuming if they were AEFW they would have starved out by now.

Any ideas? Biggest are 3-4mm, lots of tiny ones. I did dip the leather- assuming these came in as eggs.

Acoel?

These are the nuisance acoel type.
First defense is to siphon up as many as possible. this is one that a lunare and melanurus wrasse will eat.
Many resort to chemical treatment with flatworm stop BUT again siphon then upon treatment siphon up dead ones daily. IF not, toxins can be released into tank

I hadn’t realized there were nuisance acoel types? Are they predatory, or more unsightly if they hit high population density?

this is a coralQT, so no fish. I’ve also been reading chemical treatments are largely ineffective because of the reproduction rate and how fast they can bounce back if even a few survive

Uugghh

Population issue. They reproduce quickly and congregate on corals

thanks

So annoying. Ok, I don’t think they are at smothering levels. I can freshwater (Temp and ph matched RODI ok for this?) dip my coral and take a toothbrush to them right before I transfer to Display, and plan on a wrasse for control if any get into Display.

Any idea if mandarins or flasher wrasses eat these guys? They are already on the list

Flasher may, freshwater has no effect and continue with wrasse as there will likely be eggs left somewhere by the flatworms
