Do you have any dmg on any of your corals?

 

[Skaterbarney]

not that i know of everything looks fine do you have any idea ?

 

[Greenmaster]

No but if it isn't harming anything then it is probably okay... I would watch closely though. Has it been in the tank long?

If I didn't know any better.. I'd say it looks like the tentacle of an Octopus. But I doubt it is.. so I'll put my money on some type of sea slug.

They look to me like a mat type of zoas, or even a type of sponge.

its not a sponge, or zoo because it only comes out in the night time! its some sort of sea slug or a type of snail. i just want to know if its harmful because it was wraped around my prize zoos...

I would extricate it from my zoas if I were you.
