Help me identify these

[Sunshine518]

Hey reefers,

I bought a new tank recently and set it up with some live rock. The rock has some small coral patches on it and there are a couple creatures which I need help identifying.

-The first picture is my setup
-The second picture shows a patch of small tree-like coral growing in a patch with green tips.
-The third picture shows a frag at the bottom of my tank with mushrooms(?) and a white living creature on the left side which reacts to movement.
-The 4th picture shows my sea urchin...Wondering what subspecies he/she is.
-In the 5th picture is a white/brown/tan blob which has small glochid-like(plant guy here, it's the best word I can describe them as) spikes at the bottom ; I'm guessing they're used to anchor it.
-The 6th picture is this orange coraline-like stuff on the top of my biggest rock. It glows under the moon light LEDs.
-The last picture shows rust/reddish colored leather-like stuff growing on the side of my biggest rock. Also you can see in the top left of that picture some creature which looks like a mushroom - that was placed there and isn't growing into the rock.

I'm new to the hobby and have NO clue what the heck I have. Any help identifying these beautiful creatures would be much appreciated.

(PS most of the algae has been scrubbed off after I had taken the first picture.)

I bought 60-ish pounds of live rock from a guy on craigslist for 20$. That big one was the best looking rock of the bunch.

Urchin nem stomatella sponge, corraline.

The daisy polyps are the only thing I’d remove. They can spread very very quickly.

Nice score !

Can you clarify which pictures you're talking about?

Urchin nem stomatella sponge, corraline.

I'd take the heater out of there so that urchin doesn't crawl over it and burn itself not a fan on DT heaters.

From what i can see sponges of some type.
Clove polyps not completely sure they are rough looking.
Idk if that a snail or another time of sponge lol.
Looks like a mojano nem which are considered pest to most because they spread like aiptasia.
Rock is very alive though if you like all the extras.
