Myxicola worms?

[fib]

At first, I thought they were sponges, but they have developped in the last few days.

What do you think, are these Myxicola worms or Ascidiella or Palythoa or what else?

 

[fib]

bump. Some kind of zoanthus maybe?

They look like bleached zoas or palys to me, not sure which though. Put one on a frag plug and give it some more light and see what it looks like after it recovers.

+1 for bleached palythoa

Ok, thank you, I'll do that!

Well, in a week, they got new colors and have grown a lot ! Still palys? Are they invasive?

 

[Privateye]

Palys for sure! Free coral!

What it comes down to is whether you want them or not. They will multiply. So far we can see the brown returning, which is the first step, and there are certainly brown palys out there. But given a lot of light, it's still possible they'd get some green in them. They could be nice palys, or they could just stay brown. Only stronger lighting and time will tell for sure.

I had some palys on my main rock scape and they took it over. I would just put them on a island rock in the sand bed and let them grow but make sure they don't touch any other rocks.

Yeah, under stronger blue light, the center is green!

I could do that. I also still don't know if I want things full of palytoxin in my tank. Ironically I wanted to avoid Zoanthus for this reason...

 

[winzig]

not all zoas have palytoxin as far as I have read

Another five days !

Another five days !

Once they’ve spread, you’ll never be able to remove them just a heads up. I had some mixed in with my zoas and no matter how many times I try and remove them they always return and smother my zoas for light.
