HELP!!! ID Please!

Found this critter on my glass by my mag float. When I moved it, it fell to the ground and creeped away onto a rock. It is larger than a quarter, light grey with dark spots all over. It moves like a slug. I did not see any kind of mouth on its under side but it has an opening on top that looks feathery like a flower and it closed when I touched it. The closest thing I could find online that looked like it was a spotted nudibranch. Can anyone tell me what it is and more importantantly if it is safe to have in my reef tank??? Thanks so much!

I agree it looks like a nudibranch. There are soooo many different ones its really hard to say what kind or put a name to it.

It appears to be Dendrodoris elongata, a type of nudi. I don't believe they are particularly toxic, but I'm not sure if they are a predator or not.

OK, so do you think it is ok to keep or should I be trying to remove it?

Hey, thanks for the link, I think I found it!

Discodoris fragilis (Alder and Hancock, 1864)
Location: Alexandra Headland, Mooloolaba, Sunshine Coast, Queensland Australia
Size: 95 mm
Depth: Intertidal found under rock
Temperature: 26 C ORDER: NUDIBRANCHIA
FAMILY: Discodorididae
brown

I will do some more research though because it did not say anything about what it eats or does.

 

[str8juizy]

Oh, you found it too! Ha ha! Let me know if you find anything else out about it...

 

[str8juizy]

So, I guess it is a Discodoris fragilis. I found that they eat sponges which I have many of in different colors and sizes, the largest one being a red tree sponge that has four branches and stands over a foot tall. I think I will keep the little guy around unless I find that my sponge growth cannot cope with his appetite!
