Who'd of thought

Just when you thought you had seen everything there was to see in your tank something new pops up :lol:

Anyone want to take a stab at IDing this thing? its about 2 1/2-3" long and moves pretty fast, albeit slug like

Some kind of nudi, maybe "dendrodoris nigra"? Cool 'hiker... eats sponges.

Neato :cool:

Found this on wetwebmedia, looks like your dude, about halfway down the page: http://www.wetwebmedia.com/nuididf2.htm

It appears to be a species of Dorid Nudibranch and if it was in my tank, I’d remove it. They don’t usually survive long term because of their specialized diets. Worse, is that when they do die, they can release some nasty toxins. Please see more information regarding this at WWM:

Thanks

From that info it does indeed seem to be Dendrodoris Nigra. It appears to be finding what it needs in my tank and hasn't done any visible harm so I left it.

I'll probably never see it again :lol:
