Is this Aiptasia or Baby Feather Duster or what ?

[streetrodder007]

I have noticed this very small thing growing in a small patch of Pipe organ I just fragged. I have never had Aiptasia but I am wondering if this is it ? Also its right next to a feather duster than has not come out of its tube in roughly 2-3 weeks ? Any thoughts ? thanks, Bill

What you see is commonly called a "pineapple sponge".

Nice ID rat! My sump is covered as well.

I dont think I have ever seen one before. I wonder if it was a hitch hiker on the pipe organ ? And will it hurt the tank ?

[AZDesertRat]

They should not hurt anything. I find they come and go in my sump and overflow.

Thanks for the info Guys !

I wonder where they come from also.

My HOB skimmer is always full of them! I have had them grow on the walls of my tanks in the past too.
