Flatworm id

Flatworm id please

That's a polyclad flatworm of some variety, possibly a Euphyllia-eating Flatworm, but I can't say for sure (I need to brush up on polyclads again) - regardless, it's definitely not a keeper:

this is definitely a polyclad flatworm of some kind - Euphyllia Eating Flatworms are one kind of polyclad flatworm.

Regardless of what kind yours is, it likely either feeds on corals or mollusks (snails and bivalves, including clams), so it is likely to be harmful.

Get that thing out of there! Definitely a coral-eater of some kind.

Brill dipped all my torches and frogspawn reckon about 5 fell off was expecting more. Will dip again in 4 - 7 days

Look for eggs around the skeleton near the heads of your euphyllia. Little yellow dot/circles.

Dipping won't kill those and they will continue the cycle unless you get the eggs.

Did anybody ever get a Positive ID on this flat worm? I believe I currently have a similar species in my tank current.

Can you get a pic of the top of this critter (rather than the bottom, as is currently pictured)? I ask because the rim/skirting around yours makes it look like it may be a chiton rather than a flatworm.

Oh dang, I didn’t remove it from the tank when I spotted it last night and lost that opportunity. The photo I have is all I’ve got of it.

Well, keep an eye on your corals and snails (likely targets for flatworms), and if the critter pops up again, snap another pic of the top. Chitons basically look like a rolypoly on the top and a snail underneath.

Thanks for the advice, I’ll keep a close eye out for it.

Was able to spot the organism again this evening with the help of a flash light, looks to be at least two of them confirmed in the rock work that I was able to see. I sort of see the “rolypoly” appearance you were talking about but I can’t for sure say that’s what these are.

Just adding some types feed on Tridacna (Clams), some larger snails commonly found in the trade.

The pics are too blurry for me to see if it has the segmentation of a chiton - if you can remove one safely for clearer pics, that would help. You can also google chitons for comparisons- some have very obvious segments, but some have much more subtle ones.

Also, if it moves slow or fast can be a good indicator - chitons tend to be slow while some predatory flatworms can be decently fast.
