A couple id's from my 125...newer rock

[browniebuck]

The first is a pinkish colored sponge (I think)...I initially thought that it was cyano, but I can tell that it isn't (it is a lighter color).
The second is ??? Could be majano (though I don't see any tentacles around it) or could be some type of coral polyp, the picture isn't very good. It hasn't spread or moved, but it has grown in size. It is at the top of my aquascape and will close up when I feed the tank, it kind of shrivels up over top of itself.
Any help would be great.

The first looks like a sponge to me. And the second looks like a zoa polyp. Are there "tentacles" around the outside rim?

There are tentacles around the outer rim of it, but the base is longer than most zoas that I have seen. I was thinking that it could be a button polyp...but I am not sure.

YUP...first 100% sponge
on the 2nd....does it retract...or just close when touched? that should help you decide which one it is

 

[browniebuck]

it kind of "folds up" (the outer rim folds towards the center) when there is food...not sure if this is how it eats or if it doesn't like being touched.

its a zoa, I have the exact same ones. Zoaid.com calls them copper palys I think

zoaid LOL. god I hate that place. they have 15 different names for the exact same zoanthids. zoaid calls them many things I bet. (fret I am not laughing at you I am laughing at zoaid, I just hate when it goes from what it IS, to what its called.)
OP it looks to me to be some sort of palythoa probably a Palythoa Heliodiscus IMO.
as for the first picture I agree its a sponge of some sort (with over 5,000 species I couldnt nail it down exactly for you but its most likley harmless as most are, thought there are a few clam boring species etc.)

the "tentacles" around the outside edge aren't that long and the color is more or less a solid orange-ish tan color.
"it looks to me to be some sort of palythoa probably a Palythoa Heliodiscus IMO."
reefkprZ...I looked that up and it is closer than the other suggestions. I am having trouble finding anything with a foot or stalk like this one has...it has a stalk/foot like an aiptasia does, but it is definitely not aiptasia or manjano.

I got some new live rock with the same exact thing on mine, except there are about 12 of them on there, mine are a bit of a copper color though and dont like to be touched, they close up when I do.
