A new friend

[Michael Stetz]

I am new to this forum and to saltwater in general. I found this in my rock the other day. The only new addition to my tank before I found it was a rose bra. Any ideas. It is smaller than a dime.

Any advice on what it might do to my tank and how to remove it would be appreciated as well.

Here is a link to a video of it on YouTube
Thank you

Looks like it could be a mushroom of some kind. I'd keep an eye on it, and try to get a better picture.

Google pineapple sponge. That's kinda what it looks like on my phone at least...

Could be a sponge. Sometimes they have mouths that open and close.

I don't think its aiptasia. Looks like maybe a sponge.

its a sponge. Very common. You will see new ones all the time.

Wow thank you guys for the quick replies. This forum rocks!

It does look a lot like a pineapple sponge but a lot smoother looking than most of the ones I see on Google images. It sounds like they are not harmful so I guess I'll let it go for now it would be very hard to reach it where it is.

I started my tank with dry aquamaxx eco rock so I wonder where it came from?
