Another sponsor told me that that aiptasia-x may kill them. The limpet is in my overflow...limpetting around.
 
Jenn I offered it to you; Denise, if Jenn doesn't want it, it's yours. I plan to hit Jenn's sometime on Sat. Interesting, I am seeing small brown spots where the sps was white. It's either brown algae, limpet hickies or the polyps growing back. My money is on the brown algae!

Tony, you're a hoot. Aiptasia-X may kill the hemorrhoids - oops I mean hydroids? Everything in my tank is becoming a hemorrhoid. I took the rock out and scrubbed the living daylights out of it after using a tweezer to get most of them off the rock - you know what that is like when I can't see a darn thing up close or tiny? I put the rock in the 34, thankfully that system is so much smaller and has maybe 10 pounds of rock in it, so if the darn things spread I will just cook them.

Thankfully Chris at Einsteins helped me with these little boogers. He also convinced me not to throw the towel in.
 
I am about to feed my two aiptasia some poison. Do you have a a pic of the roids?
What exciting lifes we lead. God forbid a day goes by without my arm in the tank! :-).
 
The have a thread-like stem, a little dot in the middle that looks like a cricle of eye lashes. They are clear. There most be 400 of then in a 6 x 6 inch area.

The pics of the hydroids are on the first post in this thread. Kill those aiptasia because you dont want them things to get out of control.

Today was the first time I used latex gloves to put my hands in the tank, I generally dont but did not want to take a chance when pulling the rock out.
 
I just knock them out along with a few bottom polyps. Then I used the remain dose to remove my ear hairs! I don't see your hydroids.

Those are mini feather dusters.. I used to have a bijillion in my 180 a few years ago.. I think I even made a thread looking for things that would eat them..
 
Thanks Doc, what differentites them from the hydroids - their color? Over ll appearance?
My assumption is that they are harmless or should I get rid of them?
Thank you.
 
The feather dusters should have a hard tube like base. Usually white, but can always be a different color in some spots because of coraline or other algaes
 
From the pic it looks like at the base of them its kinda like a cardboard color, correct?
If so they are FD's..

If they are really getting thick cut down on feedings a tad and it will starve them out perhaps..
 
They look like feather dusters to me. But again the picture isn't very clear.

There are 2 white calcareous tubeworms in the the first picture - away from the cluster - those are fanworms = good.

The reason I think the grey clusters are also fanworms is their shape. Cluster dusters have soft pliable tubes - they feel kind of rubbery - they are similar to the giant Hawaiian Feather Dusters sold individually that are much larger. Those small colonial dusters live in colonies.

Do the "feathers" or crowns retract quickly when startled? If the crown retracts but the tube remains where it is, they are feather dusters. If you can pick one or two off and bring them in I can take a look.

Looking more closely at the second picture I'm almost sure they are feather dusters.

Hydroids can come in several different species/shapes, but they often look like tiny button polyps, sometimes they seem "fuzzier". They may also resemble tiny anemones.

This is a picture of a common type of hydroid:

Here is another pic of some among some yellow star polyps:

This is a photo of a single small feather duster:

I've looked a bit for a picture that resembles the ones you have but I can't find one... but I can tell you that a tank we maintain has literally thousands of them that look very much like yours - gray or brown pliable tube, and white or brown "feathers".

Here's one sorta kinda...

They show the pliable tube variety - those are a bit prettier than most.
