Oh that's awesome! My Tank is cycling and that was just on some live rock I picked up

Ok so the bottom one has turned into a tube with black and white stripes on it no mouth or anything roughly 2cm long and it retracts at night back into its bubble shape, is it still possibly a zoa?

A picture would be helpful

 

[Ogi]

I will post one when I get home from work

I cannot get a Better photo my camera refuses to focus, so i doubt this will be the picture we are looking for, it has slightly retracted and i cannot see the black stripes on it now

Picture is no help, I'd guess that it's probably a feather duster from your description. Post a better picture when you get one.
