@KGR: it's some sort of hydroid polyps.

The first two pictures look like Hydroids, the last one is Yellow polyps. The video appears to be a Peanut worm.

Tunicate, harmless.

Any ideas on the type of hydroids and i knew it was. Polyp just wondering if maybe those are babies.

I have a couple of hitchhikers that I am hoping you all can identify. The first is a small red tube about 1/8 to 1/4 inch long that lets out a long streamer that is about 2-3 inches long. I only noticed a couple of them but now there are about a dozen and no longer confined to the rock they started on.

Red Tube

The second item appears to be some form of brittle or serpent starfish but has 6 arms instead of 5.

The hydroids are not the dreaded photosynthetic variety, but other than that it's impossible to identify them from pictures.

I would give this an 80% yes - could also be limpets (the image is rather small for me to be sure)

[Sugar Magnolia]

Yep, it's some kind of pest anemone.

Olive Green Clear Hard Eggs?

Olive Green Clear Hard Eggs?

Found these olive green eggs?? in a couple of places. One group attached to a polyp frag and one group to a small piece of LR. They look jelly like to the eye but they are hard to the touch. Pic attached... Any ideas?

The red tube is a vermetid snail. That's a mucous netting you see coming from them.

Your stars are just cool little "micro brittle stars". They'll stay at that size.

IDK but the sharp pincers says he is not too good.

Just found this this morning in a zoa frag I put in my tank just now. While I do see several feather dusters on the frag also, just not quite sure what this is? FYI I'm talking about the brownish little branch sticking up.

 

[alexander_ktn]

Looks like some sort of clavulariid (like glove polyps), they are harmless but might spread.

 

[homer1475]

Ill dig out my DSLR and see if I can get a better pic.

 

[homer1475]

Just found this pic online(suppose I should do some more leg work of my own instead of just asking in here.).

Thanks alexander_ktn you were spot on by that pic.
