Id needed, flatworm?

[Raynn]

Hi,

Today, while cleaning my tank, I noticed something that looked like a flatworm, though I’m not sure what it actually was. It appeared in a group and was difficult to remove,I had to use a scraper to get it off.

Does anyone know what this might be? Thank you for your help!

A is bubble algae and B looks like some other type of macro algae. The things I first though were the flatworms you meant rather look like "leafs" on this image. It would probably help a lot if you can get an image under neutral/white light.

Yeah, white light would be helpful here; I am not seeing a flatworm - as above, A is either bubble algae or possibly tunicates (white light would be useful for telling which, but if it was green it was probably bubble algae); B looks like it's probably early growth of a serrated Caulerpa species.
