As a follow-up, I took some more pics. Does this look like eggs? Dead center in the pic and on the bump to the right of dead center.

I don't know what it is to be honest, but the zoa-eating nudibranch egg masses look more like this: http://s744.photobucket.com/user/jays333/media/WhiteSwirls1.jpg.html

This is a strange animal that came in on my live rock. It seems like a sponge, but it reacts to movement, sucking in, closing it's siphons (one in the front bottom and on back, top). Isn't that odd behavior for a sponge?

Sorry for the bad picture. But what is this? Good or bad? I've seen a few in my tank. They move around like jelly fish. It's the thing just bellow the polyps. Kind of looks like a jelly too.
(Edit: circled it and zoomed in. Still a bad picture tho!)

It's really hard to see in the picture, but it might well be a jellyfish - Nausithoe sp. comes to mind as species that occasionally pop up in tanks (there are polyps somewhere on the live rock that strobulate into jellies). They are generally considered harmless.

I can't really say, since I am no expert in isopod identification (they are definitely not the "classical" white and super bad cirolanid isopods), but they seem rather big, so I'd probably discard them (or keep them in a nano tank) for fear of them munching on (sessile) livestock in the display tank if there isn't enough other food available.

Hard to say without a picture, but the 6 tentacles per polyp (as opposed to a number divisible by 8) suggests a hexacorallian - i.e. an anemone or a scleractinian (if it has a calcium skeleton).

i will try to take a picture. but they are really really tiny . they do have a green dot in the center. might have 8 tentacles. will double count it. yes it has a calcium shell . there are 2 of them. so i will assume since it has a calcium shell its should be a pest and move. so it shouldnt be a problem or a pest . is that correct

Yes, if it has a calcium skeleton it should not grow fast enough to become a pest quickly, no matter what it is.
And a photo will be good.
Cheers, Alex

Hidden cup coral maybe? Phyllangia americana.

is what I thought....but the picture is tough to make out...but if the rock came from Florida...is most likely so....
