Need help identify a new alien in my tank

74maddox · Feb 2, 2020

I've had my take set up for about 9 months, no new rock or anything for at least 6 months. About a month or so ago, I found an "alien" on the underside of one of my rocks. It hasn't done anything- no growth, no movement. But, what IS it? I'm attaching 2 pictures in hopes that someone might know what it is. Thank you!

Could be a sponge???

ok... let me explain, when I first checked there was no pics, just links, and Mic said "oof" so I thought it was a joke AND it's in DIY not Hitch Hikers.
Sorry.

Is it soft or hard to the touch?

That either looks like a very very rare form of aiptasia or a sponge

I apologize that it's in diy, I'm new here and learning to navigate.

No idea, I haven't touched it, I would assume soft though, it looks "fleshy"

Might be a sponge.

Sponge? Where is @KJ at? He would probably identify it. Possibly down to the scientific name lol

Sponge. other possibility is Macro algae but texture points to sponge

Also, it's less than 1/4" around...
