Tubular growth with bright green heads that retract

[MonsterReef]

This just showed up on the back of my clove and Kenya tree rock. Any idea?

 

[kschweer]

Any chance of a better picture?

 

[Triggreef]

hydriods?

several different types google a few and see

 

[Nick.B]

You just described colonial hydroids perfectly. That woul be my guess without a better picture.

[eliramos]

Those are bad?
I have those by one of my leathers!

 

[reeferfoxx]

Clove polyps. Invasive but not bad.

 

[MonsterReef]

So more of the ones already there are different type?

 

[MonsterReef]

Or*

 

[reeferfoxx]

Oh! Sorry. I really cannot see what you are taking a picture of lol. Is it possible to turn the pumps off, smash your phone against the glass, pinch zoom and tap the center part of the screen to auto focus? Sorry, not askin' much

 

[MonsterReef]

Lol. If my camera was waterproof would be easier

I second that.

That coral was mega dipped bc of an infestation of bristleworms before it was added to the tank. And the tubes are hard like a feather duster tube.

 

[Triggreef]

Let's try different way. Does it look like these? If so, colonial hydroids yes bad, Google them for more info. I've used reef epoxy to smother them with good success.

 

[MonsterReef]

No not at all

 

[Triggreef]

Vermetid snail? Wouldn't really call them green but i suppose could be green from algae growth. Sometimes put out a stringy net to catch flowing food particles.

 

[MonsterReef]

Nope. It's a coral of some sort. Isn't mobile. Just curious what it is.

Does it look like this with 8 fronds on the polyps? I was told that this is a pipe organ coral. Pipe organ corals are one of the few octocorals that produce a hard skeleton. In this case reddish coral colored tubes, one of which can be seen on the upper right of the clump. I believe they are the only coral that deposits this color skeleton. Most YouTube videos show them with green fronds. These aren't established enough to see more of the tubes or for me to make a positive ID. The centers look mor green than in the picture and are florescent under UV.

 

[MonsterReef]

The centers look like that but it isn't old enough for the fronds to be that long yet I suppose. Thank you!!

 

[Mark Shelly]

The fronds are about 3/8 long on top. But in the newer polyps at the bottom, they are only an eighth. Are there 8 fronds? (I know that is probably not the correct term.)
