What is this

[absolutecarrot]

These thing have been showing up on my glass does anyone know what they are, thanks

 

[this is me]

Flatworms. Likely the LPS eating or SPS eating type.
Not what you want to hear. And unfortunately, I don't think it's the non coral eating type since the one I see here is dark. Dark flatworms are usually not good news.

Do you dip or treat your incoming corals?
Bayer will eliminate 99% of pests and the remaining 1% are eggs which you have to scrape off and clean an eye on the corals.
If the coral can't survive the Bayer dip, it doesn't belong in my tank.

Do you know if six line wrasse eat them, I mostly see them on the glass some are more white then others. I scrape them of and it kills them, I haven’t seen any on my corals so far

 

[this is me]

I think the sixline will be an issue itself.
A yellow coris wrasse might be a better choice.

Can they go it a 20 gallon

 

[this is me]

I wouldn't since they can get pretty large. 4-5"

Since it's a 20G. I would take all the corals, Bayer treat them. Place them in another tank and let your tank go fallow for a couple months.

I will definitely dip them again

Looks like a polyclad. I would look at the based of any LPS corals to check if you see more of them. +1 on the Bayer. that should do the trick.

I catch them off the glass with these. Works well if you happen to see them. https://www.brineshrimpdirect.com/sieve-combo-set

Do you get any LPS such as torch, wall hammer or wall frogspawn coral lately? It looks like those LPS eating flat worm

 

[absolutecarrot]

Do you get any torch or hammer coral lately?

No not for over a month

 

[dz6t]

It takes about that long for them to repopulate from one or two.

So what do you think they are

 

[dz6t]

You can dip all the torch, hammer and frogspawn with seachem reefdip to see if any of them fall off. Then do a full tank treatment with flatworm Exit.

Thanks I’ll get some flatworm exit

So what do you think they are

From the shape and they are on the glass, I think they are LPS eating flarworm, which becomes very common lately locally. I helped several people treat their tanks already.

In most cases, these worms were found on wild Euphyllia coral especially torch coral. They responding to iodine dip such as Seachem reefdip very well. Sometimes they even live inside the mouth of torch coral.
