Hi

Does anyone have experience with these flatworms, if so -- which ones are theses?

At first i thought these EEFWs, but having spotted them on multiple corals I'm not quite sure.

Welcome to R2R!

I'm not sure about the those worms. Maybe time for a wrasse? :D
Thanks!

I already have an Melanrus Wrasse, although it shows no interest at all haha. Perhaps it's time to trade it in for a sixline.

Does anyone else have an idea which flatworms these could be? They don't completely strike me as the EEFW, Planaria or Waminoa -- and everyone who has given me advice, has suggested it being one of those I just mentioned :downcast-face-with-sweat:

I think the EEFW would be the closest but they're usually larger and grayish. Those are Polyclad flatworms which the body looks similar so I'm thinking in that family.ive had good luck with Springeri Damsels eating flatworms and they tend to be on the peaceful side of Damselfish.

I vote for yellow wrasse rather than sixline! Much less aggressive and prettier too!

Welcome to Reef2Reef!

Whoever said Waminoa was who I agree with here - they're pretty diverse in color, but the shape and finding them on a wide variety of corals would be in character for them.

Fig. 2 in the link below shows some similar (but not quite right) specimens to give you an idea:

I've looked into it, many thanks!

Unfortunately, I wasn't able to find much specific on the Waminoa flatworms and possible treatment:
Coral magazine however has a post where the use of Lanthanum in-tank is discussed, but beside that I did not find a lot. The in-tank interests me, as the main LR holds several colonies where the flatworm side. Pieces that I unfortunately can't take off. Do you (or anyone else) have experience with this method?

The post also states that biological options such as wrasses and the Blue Velvet Nudi are not really that optional as a sole solution, but I guess it also wont hurt to try. I'll take a look at the Yellow wrasse!

Lanthanum Chloride?

They use that to lower Phosphates I believe. I know of several people that have used it successfully in the past for Phosphate reduction, but I don't know anyone that has used it for flatworms.

Sorry, meant to list this info in my initial post but didn't have time:
Waminoa flatworms are photosynthetic (much like corals, they have symbiotic dinoflagellates living in them) and reportedly feed on coral mucus (not the corals themselves), so they tend to live on our corals - they're essentially harmless, but in mass numbers can basically smother the coral by blocking the light from getting to them.
Looks like it may be a Waminoa sp. - they are known to feed on the coral mucus rather than the coral itself of corals in the family Euphylliidae, as well as mushroom corals. Theoretically, in large numbers these guys could cause problems for corals like stated in the quote* below:
"Apparently, acoels can harm corals by smothering them, which may hinder their respiration, feeding and sediment shedding capacities."

*The link the quote was taken from:
The only confirmed effective method of removal that I'm aware of is a repeated dip and cleaning method (pull any infected corals from the tank, dip them, scrape off any worms/eggs that stay on through the dip, repeat as needed). It may be more effective if you can to dip, scrape, and then put the corals in a different, uninfected tank to wait out the starvation of any eggs/worms in the infected tank, but this may not be possible. The link below has some other ideas you can explore if you'd prefer, but I have no idea if they're effective or not:
Edit: Also, here's a link that shows some more known host corals (I would assume these will host on just about any coral they can get too to be honest).

Unfortunately, I can't take out most corals due to them being encrusted on the massive rock centerpiece. So dipping and scraping is mostly a lost cause.

I keep finding conflicting information regarding chemical treatments, some sources claim that Flatwom Exit do works, while others deny it. Lanthanum Chloride seems to be a working treatement specific for Waminoa sp though.

I will definitely buy a yellow Wrasse, does anyone know to happen if Blue Velvet Nudi's eat Waminoa flatworms, if yes, I would love buy one too.

My guess is that either 1 - the effective treatments were done on misidentified species, or 2 - that some Waminoa species are effected by it while others are not. If you try the lanthanum, let us know how it goes; it's always good to have more feedback/data.

I don't know if they eat Waminoa species - if you decide to try one and find out, be sure to have a plan in place to give the Blue Velvet to in case it doesn't eat them or in case you run out of flatworms for it to eat if it does. Also, if you decide to try it, let us know how it goes.
