Any ideas what some of these are?

1)This sponge seems to grow on everything.

2) A black and white sponge that has been on this blast for two years.

3) Barnacle?

4)Barnacle

5) a red and black/blue sponge

6) A white film like sponge

3,4 appear to be some type of mussel or oyster.
5 maybe a colonial tunicate. Looks similar to: Botrylloides giganteus

My few cents:
1: probably a sponge, tough to tell
2: Sponge
3: Jewel box clam
4: Jewel box clam
5: Colonial tunicates
6: I'm guessing sponge, but could also be tunicates - if they react to touch, it's the latter

1, 2, and 6: Yeah, those are sponges of some kind.
3 & 4: Bivalves of some kind (there seems to be a third just under the one pointed out in 4).
5: Probably colonial tunicates of some variety (though I can’t quite see it clearly enough to rule out a sponge).

Any idea is sponge 1 is a problem? It’s growing all over the place and on my maxima clam shell.

If it’s growing everywhere, then it may be invasive; not necessarily harmful, just fast spreading.

As a general rule of thumb, unless a sponge start growing over and smothering things (like corals) in a tank, it’s probably harmless.

Edit: I’d assume the sponge is harmless at this point.

It seems you have your answer but where did you get that rock? Those are really nice!

It is only one have like 5 pieces in the tank. Came from Tampa bay saltwater.

I’ve heard good things about them but I am sold on them if I upgrade after seeing yours.

As long as you’re comfortable with the critters it brings. I love the rocks and they speed up sps tanks so much. But there is no escaping aiptasia and so on. Berghias and Copperbands are my top picks for live rocks

I started reefing in the mid 90’s and ran a tank for 16 years. Gorgeous live rock back in the day ( no one used dry) and there were no frag plugs and all the corals came on small pieces of live rock. I used sit with a flashlight and watch all the critters, it was almost as fun as watching my tank with lights on. When I set up my tank over two years ago I got my rock from a friend’s sump ( been sitting in there for a couple decades), plenty of bacteria for an instant cycle but few critters. I have bought and added bristle worms, spaghetti worms, amphipods and micro brittle starfish. I’m missing the little feather dusters.

You know then back with the old fiji rock.

So much cool stuff and over the years I’ve gotten to the point where pests are not as big of a deal to me.

Much more fun to investigate with a flashlight.

Now if I could just get po4 down a little from 1.7 ppm and no3 down a bit from 70ppm. Haha
