What is this?

[Musiker]

Hi all,
I have spotted an animal like this, cleaning my Aquarium glass, several times during the last 6 months.. This morning I saw two more and got curius to what kind of animal they might be?
The ones I spotted this morning is only 4mm long, but the first one I saw was maybe 1-1.5cm long, but otherwise identical.
The mouth is in the lower part. And there is no shell on the back from what I could see:

Stumped me....

I am also at a loss. Don't even know what type of animal I should google for?
Do I need better pictures? I am on the lookout for the bigger specimen, but with only a 18-105mm lens for my camera... I can't do much better of the small ones?

Touch one to see if there is a shell. It appears they have a shell under their flesh, but I could be wrong. Neat whatever they are.

I thought maybe a bubble shell?

Doesn't quite match, but....

Thanks elysia! I think youre right it must be some kind of Bubble shell! The Haminoea sp looks most like the ones I have (of the two you link to..)
I will go hunt for a bit more information..
Thanks!

No problem. I'm not familiar with the colors of the various bubble shells, so I just had to open various species pages on the seaslug forum to see if there was anything close -- the shape looked like it could be a match, but it can be hard to tell from some photos. Plus, I'm not too familar with what is available in Denmark! Just keep us updated and post any other posts you have -- I am always interested in anything slug-related. And the man at seaslugforum may be interested in receiving any clear photos you may be able to take -- his response time varies, but he can give you good information about your animal's identification.

See the two small ones trailing eachother on the glass now.. Hope I see the big one again. Then I will be ready with my camera.
The snails have come in as hitchhikers.. Most likely with a SPS coral. And I have only bought a couple of them in the last 6 months.. Doubt it is from a frag..

Can't get better pictures of the small ones without a macro lens..

Believe it or not, I was going to suggest bubble-shells, but didn't want to influence anyone trying to figure it out to the species. I put my vote in for a bubble shell, although I do not have any personal experience in their care, only one of my text even mentions them.

I thought it resembled a small cephalopod i saw in the Caribbean but it has no tentacle formation so yea.

So are they good or bad?
Cause they are cool

i know thats a bad shrimp just forgot what its called. it will eat anything it can

 

[YoungReefer06]

It is a Saron shrimp, aka monkey shrimp. Not reef safe. And if you care to know I believe it is a male.

On the bubble shell subject, not to neglect the shrimp:

It will be an algae grazer/herbivore.

Cheers,

Thanks Don for the link to your search. Its becoming obvious to me that I am going to have to start buying corals for the sake of the hitchhikers -- people on here get the coolest hitchhikers!
