Another hitchhiker to ID please!

[Ricordia]

Me again. Thanks very much to all who helped with my little anemone.

This morning I saw this little guy on the top of the GSP I aquired for my 20 gallon nano a little while ago. Any ideas? He's about 1.5 inches long.

It appears to be a nudibranch. See the article below.

Yup. And a cool looking one at that.

Looks more like a Sea Slug to me.

I was leaning toward sea slug myself, but I've only seen black ones. Aside from the eye stalks, I don't see any frilly bits. Does anyone know of a good site that'll help me narrow this down a bit?

Most likely a Flatworm.
Need a better picture but it appears to be a species of the genus: Pseudoceros.

Hmmm Pseudoceros. "False horn" makes sense.

Flatworm. That's a word that really gives me the shivers! I suppose there are only a few bad species, and this one doesn't look like the bad ones, but...

I'll take more pictures when I can. At the moment it's down in a crevasse in the GSP rock and I really don't want to poke and prod at it to come get it's picture taken.

Is it worth keeping, bad flatworm or not?

Well there are close to 20,000 species of flatworms. If this is a species of Pseudoceros unfortunately their diet consists primarily of tunicates so the likelyhood of it surviving long term in your tank is grim.

Awww it's kinda cute

 

[Ricordia]

I managed to remove and photograph this little guy. Looks like Pseudoceros is a good id to me. I didn't put it back in my nano, cuteness not withstanding; I don't want to take the chance that it will release toxins when it dies and I apparently don't have anything to feed it.

I just posted a new picture in my nano-buildoff thread: http://www.reefs.org/phpBB2/viewtopic.p ... 229#936229 (shamelessly forcing people to look at my buildoff thread) of another one of these guys! This one looks very similar to (but is about half the size of) the one posted above. I really have no idea how it got there, and how it survived if it's been in there as long as I think it has.

Any other ideas? :lol:

couple of good id sites.

Thanks for those links! The sheer variety of species is a bit overwhelming! I was mainly wondering what it is eating, since as far as I know there aren't any tunicates in my tank at all. The little guy was spotted by my parents on Christmas Day, so it *has* to be eating something!

Ricordea.
