What the heck is this?

[SlicVic]

I just got a framer acclimated and put them in my tank the next thing I know I see this creature on my tank wall! Scared The Living Daylights out of me! Looks like some kind of a snail or something can somebody tell me what it is and is it dangerous do I need to take it out?!

Could be something like a stomatella snail, but my guess would be some kind of nudibranch or flatworm - do you have any other pictures of it?

Pic is not clear. Take it out and put in a bowl with air stone until we know what it is.

Nudibranch or a slug hard to see

Looks like a nudibranch of some kind - the photo isn’t clear enough to make out what kind.

Looks like,well similar to some sea slugs I had on my gsp ,removed about 30 in first 3 weeks of having found first one

Whats this ? Sea slug/ cucumber ?

Just found 3 of these sea slug/ cucumber/nudi looking things. Hasn't got the frilly Gill things that nudis have on their back so probably rules that out. It's on a gsp that just bought and camouflage quite good same colour as top of gsp frag like browny/ white,2 are very small like 8-12 mm long...

I'd say marine flatworm rather than nudibranch, and given the pronounced striation of the wiki one linked, I doubt it's that one. I would start here: http://www.seaslugforum.net/specieslist.htm While an ID will take a while that way, they do have a picture for most species named, and you can probably at least get an idea of the variety that is out there.

Generally, their diets are very specific, so you don't need to be worried unless you have something that it specifically eats that you want to keep - though this isn't often immediately obvious. Sometimes they look like their food for camouflage, but not always, and if it's running around the tank during the day, it's likely that it is out of food and searching for it.

True words . I think I have the same slug .

If I touch it it turns white ?? And also looks like it blends in with the surrounding rock if moving around

Actually, I think they have the right genus, but wrong species (though the "ruffling" around the edge definitely gives it a flatworm-like appearance). The creature above looks like Dermatobranchus striatus, but with a white head and slightly more white-spotting. It might be a different species (there quite a few in the genus, including some that don't have official names yet), but I'd be surprised if it's not a Dermatobranchus sp.
