not sure what these are

majano? aptisia? feather duster?
Pic 2 and 3 are the same rock, just different angles. Pics 1 and 4 are the same unknown item, just in 2 different places.
I know pics 2/3 arent the best but i couldnt get a good zoom on them. Not worried about the blob of algae in pic 3, just the brown tiny polups growing next to it.
thanks for any info.

there feather dusters.
the third pic looks like cyano bacteria
the secongd pic i couldnt make out
behind the cyano bacteria, they are tiny brown polyps. 2nd pic and 3rd are the same, just different angles.
thanks for the ID on the 1/4 pic. I thought they were feather dusters but when i try and google them i get all kinds of strange pictures.

I'd say the yet-to-be identified things look like probably colonial hydroids. If they look like brown palythoa's but they're about as big around as a pencil lead, that's what they are. You should pull that rock out and put super glue gel over them or use a chisel and chip that part of the rock off. They are very stingy and will spread.

new pics. These 2 pics are the same rock. Pic 1 is where they are all out. Pic 2 i moved the rock and they shot inside the stems.
they are very small. For size reference, look at pic 1 from original post. These same unknown creatures on on pic 1, to the right of the feather dusters in the upper left.

It's a stingy-celled animal. Like a jellyfish that grows out of the rock... a micro-anemone perse. They sting fish. They can sting you too. They are pests and will spread like aiptasia.
