This is an odd one i am stumped.... you ??

[rockdiver]

So this morning before work my usual check on the tank and on the back wall i see this. I usually know what most of the stuff is but not this.
Any takers lol
Will try to post a video but the outer edges kinda float and it can put out white feelers.
I have no idea what this is

Almost looks like something covered a snail. like the movie the blob lol

I was initially thinking stomatella snail, but the latter pictures look like snail covered in a blob(bacterial bloom?).

 

[rockdiver]

Well I have no bac blooms the blob seems to just float and the feelers that come out are kinda wide like the snails the go into the sand but those snails are not cone shaped. But that's what I thought at first

 

[rockdiver]

In the 3rd to last photo you can see the feelers in the 10 o'clock position

Looks like some kind of limpet. Perhaps a keyhole limpet.

@KJ

He can ID it, I'm sure of it.

 

[Alexopora]

Google Lucapina...looks like yours might be a species in that genus.

 

[rockdiver]

Maybe I just looked
Sure I will never see it again lol

 

[KJ]

Fleshy limpet.

 

[rockdiver]

Never encountered one but I think it really is just a watch and see what happens approach. There’s not much material online regarding these guys. Some say, they may munch on sps but i think its not 100% proven fact. So you could just leave it watch if it does eat any of your corals and move if necessary. Or you can be proactive and rehome it into a refugium or sump.

Don't know, but it's COOL

 

[rockdiver]

Ya it is cool looked real quick this morning since I was running late didn't see it. But all the corals are fine.
It was pretty big bigger then a half dollar lol

Neat, I have one it looks close enough to a limpet that I just assumed it was a good guy. Cool to have a name for it now. Mine came in on gulf liverock.
