The white things. They have been slowly growing on the rocks and walls now I see some on the Zoas.

They are just white spots with flowy legs. Almost reminds me of a jellyfish but they dont swim around they are just stuck to whatever they are on.

In my tank I do have snails a shrimp and a clown fish and coral but thats about it.

Kinda blurry, but if it is what I think it is from your description sounds like a tube worm. I have a bunch of them. No worries.

Does it look like a small white calciferous shell with little white/clear "tentacles" poking out?

Hard to tell from your pic. Do they look like this? If so, hydroid jellies, harmless.

Or do they look like this? If so, spirorbid worms, harmelss filter feeders.

Lord of the Reef- No it doesnt look like a shell. Looks like a soft white spot with soft free flowing tentacles

Sugar Magnolia-No they dont look like those two pics either

Here is a pic of them on walls

Kind of hard to tell from the pic, but I am thinking hydroids maybe? Are they coming out of small leathery tubes? If so, could be dusters.

The pic of the wall looks like pineapple sponges.

I looked up hydroids and they look the most like that. So thanks so much. These are harmless?
