What the heck is this!?

[Jeremy1973]

Ok, when I first spotted this thing in my tank, it was itty bitty..it was cool, but I didn't give it much thought. Well, just tonight i saw it again, and it has more then tripled in size! It is now marble size, where as before it was pea size. Any one have a clue as to what this is?

i cant even venture a guess so ill leave thiso ne to the pros, it is very cool looking though

here, i hope is a slightly larger pic of it.. sorry I can't get it crystal clear...it is hard for me to clean the glass where it is.

my wild guess is some kind of nudi, assuming that it moves because you see it intermitantly.

other than that i have not a clue.

There is no movement to it...from what I can tell. Unless it is soooooo slow that it moves a cm in 8 hours or something. From what I can tell, the only time it moves is when the current blows it.

could it be a tiny hammer coral? is it in the light? if it does not move then i would just let it be. see what happens. i only worry about things that move. movement implies predation.

well, just nudged it a little...no response. It does look like it is expanding a little though.

[Jeremy1973]

As of this morning, it is still there. A little more inflated, but hasn't moved. So, if it is a nudi, it is a lazy one. If it isn't a nudi...still would love some insight and guesses. And no...an alien egg does not count.

I might be some kind of mushroom but it does look a lot like a Lettuce nudibranch. I am curious though what it is. If it is a lettuce nudibranch and it is not moving then it might be a dead lettuce nudibranch.

No..it can't be dead...no dead stuff allowed in my tank..only thriving HAPPY critters! I will check on him again when I get home. He looks pretty much the same as when I first saw him weeks ago, except he is much larger. I will see if I can find the first pic I took of it. It was in the same shape it is now, just pea size.

Shriveled up mushroom? That would blow around, expand, and could be that color. Just a thought.

Doesn't look like any shriveled up mushroom I have seen..but if it was a hitchhiker mushroom, that would explain that. It still hasn't really moved, etc a few cm. But, again I think that is due to the current.

A thought for the "dead nudi" notion...if it was dead, wouldn't the hermits and bristleworms be after it? I watch bristleworms move around it, but never go for it.

[Jeremy1973]

Well, been a few days, and the thing is still there...moved over a little, but still there, looking the same as ever. So, I don't think it is alive....er...dead. So, I am left the other popular opinion that it is some sort of mushroom all closed up...tight. I will give you all status reports on this little critter... now I just need a name for it. Any ideas?
