Just noticed theres like a mouth opening and closing and has about 4 feathets coming off it? Its not a duster worm for sure

Looks like a harmless Barnacle to me.

Yep barnacle

 

[loweryphil]

Do they grow any bigger?

 

[Lionfish Lair]

Not bigger, but more can grow. They tend to not do well in our tanks and if you don't see a "feather" flicking in and out, he could already be dead.

You have a lot of cool filter feeders there... I see a tunicate to the left and there are feather dusters and I bet a lot more.... cool.

 

[loweryphil]

Tunicate? Yes it is still alive ive been watching the mouth and feathers [emoji16]

 

[Lionfish Lair]

The red is circling one type of tunicate and I believe there to be a different type of tunicate there, which I circled in blue.
