What are these?

[Panthera]

They're very small, about 0.2 inches.

That makes two of us that don’t know anyway welcome to R2R!

Welcome to R2R ! ! !

No clue but I am interested in knowing too...

 

[Panthera]

Thank you. I've been staring at rocks for a week in awe "Wow what's that? There's a thingy in there too! Wait what, is that a leg? Something is moving there!". It might be better to give the thingies a little bit time to grow, would be easier to identify them. Unless they're something bad.

Welcome to R2R. Can you try and get a better picture?

 

[SHNICI]

Amd one a bit far away, to see how big they are on the LR, and like @Lovemyreef2015 say better photo, on a macro maybe ? I have similar to this, but my are a bit hard, and they grow up under some of my LR, and they are red on color. thy are 2-4 mm big ... (similar to your one on the photo, but I still don't know what's your one, is it hard or ... ?)

Howdy! No idear on whut you have there. To throw out a generic term, I'd say some sort of that there filter feeder type critter.

I moved the rock a bit and found a bunch of similar looking things growing behind the rock. I couldn't get better pictures, sorry.

One of the original mystery things, it has several thick "branches"

The things behind the rock are long and thin

And here's the rock.

I've also been wondering about something else. How about these? They are a bit smaller than the first ones.

They are growing on a weird looking rock

The first ones that look kinda paddle-like are probably bryozoans. The others are some sort of polyp

 

[kirstyflash]

1,2,3&5 look like hydroids of some type, 4 i think is a polyp like a tubipora and the little white ‘hairs’ look like a type of sponge

Welcome to R&R! I'm not knowledgeable but I learn something new everyday! The people here are great and you will get answers to your questions.

 

[Panthera]

Thank you for the help so far. A little update. The things you identified as polyps have grown a bit, they are starting to show some interesting glowing colors. Are they clove polyps? I really hope they aren't something I should remove.

 

[reef lover]

They do look like clove polyps...

Look like Papaya cloves. Lucky you
