What the heck is this?

[Sumbub]

So I couldn’t sleep tonight and I was peeking in my tank with a flashlight and came across this.

I don’t know what this is and I hope someone can ID this animal.

Here is a video

I can’t see the video but from the pattern, looks like a polyclad flatworm.

From the video, I'd guess it's a sea hare

Thanks everyone! I tossed it when I woke up this morning. After 5 hours sitting on the counter with no water, this thing was still alive! Wow.

I'm not contesting the identification of polyclad flatworm , but just wanted to add a video of a sea hare for anyone interested:

I’ve kept sea hares before. Great eaters but so ugly. They will smother zoas. Never again.

I've only ever seen them in the wild (in southern Japan). They were bigger than softballs! And yea, not overly cute... but interesting in a reef kinda way...

Maybe there's a variety that doesn't touch zoas? The video mentions they are great for hair algae.
