So I saw this guy in the Refugium today. Roughly 1/2” in size. Clear with no coloration. I hear they eat pods? It’s listed as a neutral hitchhiker if it is ghost flatworm. It can move rather quick, I found.

I saw one in my DT awhile back. Haven’t seen it since. I wouldn’t worry about.

Yes acoel. siphon it quickly with a 3/8" tubing. If more than one , consider a 6 lined or yellow coris wrasse which will eat them. These are not a threat BUT if allowed to populate can smother sps and other coral blocking the light for production of zooxanthele which is corals energy source

I have a six line that would wipe it out if it was in the DT. If it’s in the sump, should I siphon it anyway? My current thought is that’s it’s a natural food source for the six line if it makes it to the DT.

Yes siphon- What you want to avoid is any EGGS

What am I missing? If there is a problem..?.., He would probably see more than one and there aren’t many reports of these being invasive....Not saying you’re aren’t right just trying to educate myself...

@vetteguy53081 I think your wrong in your identification of this species. I’ve done some more research on typical Acoels and does not look like that. It looks exactly like this Amphiscolops with an almost tubular portion of the body. And as I said, it moves remarkably fast. I know all flatworms are Acoels but I think you might have misidentified it as a harmful one. I have not read it over crowding corals as you warned.

@TnFishwater98 I think this question was actually meant for vetteguy. Or are you asking me?

No just asking. I had one that was “swimming” diagonally from top to bottom when I was observing with lights off with flashlight. When I researched I found nothing alarming. So didn’t stress about it. I haven’t seen one since so I was wondering if I was not getting all the info. There could be different species or there needs to be two in a tank to reproduce. I could keep asking questions but just trying to absorb more info.
Tanks!

So I just got confused by reading newer post There are two different types I’m assuming... Is the term Ghost Flatworm a bad one or a good one...?
Or should I say Neutral...?

So I’m still researching myself. Assuming that what you saw was an Amphiscolops acoel then, like me, I haven’t seen any thing bad mentioned about this flatworm.

Lol, I realized why you asked. My bad. I’m not the best ‘social media’ post’erbecause this is it. I just hit the last comment to reply my comment. I should of relayed that question to a different member. You were actually finding the info I found when I researched. So onward, is there a BAD ghost flatworm peeps should be aware about?

I also just found one of these guys in the sump of one of my tanks. What’s the consensus? Are they bad or neutral?
I have to agree with OP, they move really fast and the one I just saw has the same cylinder like body.

So I don’t know but as a precaution I siphon them out when I see one. It seems they only eat copepods. Never saw any in the main display because I’m pretty sure the six-line wrasse would wipe them out there.
