What is this . I have never seen these.....thanks

[Chris Shetler]

Foind it in my refugium.

It's hard to tell. May be a cluster of flatworms.

 

[Chris Shetler]

Thanks so I guess I should remove them.

 

[Sashaka]

Unless I know if the bug is bad, I don't necessarily remove it; however, if they are flatworms, removing them can't hurt. They're not climbing so it's hard to ID. Clear ones in small numbers are just nice protin fish food according to this conversation: https://www.reef2reef.com/threads/white-flatworms.85789/

Hopefully, they're not flukes. I don't see the V tail to confirm ID as a flatworm.


@HotRocks, can you ID? @Reefsquad ?

 

[Chris Shetler]

Yeah ...pulled one out ,and checked it out. Totally a flat worm. They were all together in the corner , so I sucked them out . If it is not one thing it's the other lol. Just worried about them eating the coral.

 

[Sashaka]

Red Planaria or red to brownish flatworms are the coral eating flatworm you want to worry about. I think you're okay. These look white to me in the picture.

 

[Chris Shetler]

Awesome news .... thanks for the info.

 

[reef lover]

Strange.. look too bubbly for flatworms .

Do they move?

 

[S-t-r-e-t-c-h]

Look like tunicates... possibly.

Also planaria don't eat coral; they can multiply enough to smother them, but they literally have to be enough of them to physically blanket the corals...

 

[Lovemyreef2015]

They look like some type of eggs.. can you list what you have in your tank?

 

[Ron Reefman]

You removed them, but did you keep them? Like in a separate bowl of tank water, so you could take more photos? I agree they do not look like flat worms to me (based on the first photo).

 

[Justin Cook]

How big were they? I have a similar flatworm in my tank (very common) and they hang out on the front glass. They look just like that but they're all very, very small. You are either a terrific macro photographer or those things were really big.

Yeah looks like tunicates to me.

 

[Sashaka]

Yeah looks like tunicates to me.

I wondered about this, but I did not see any intake and outtake holes that sea squirts all have. It's hard to tell from the pics but it seems like with so many clustered together, at least one intake would be open. Still, I know there are over 2000 varieties of sea squirts, so...

I wondered about this too. If they're always stationary, seems like a possibility...if there is life kept in his refugium (snails, fish, other life source to lay eggs?).

@Chris Shetler do/did they move? Are there any more in the the refugium?
