Um. A little help please.

So the last time I ignored a cute little worm, I ended up with a polyclad flatworm the size of my foot. So just curious if anyone might be able to shed some light on what this might be. Its only maybe 1/4" long, and the pic is the best I could do on a moments notice. I'll try to get some better pics in the near future. It doesn't seem all to fond of the light, if that helps.

It LOOKS similar to Elysia crispata but it’s a nudibranch and they can be tough to differentiate

Picture is rough but yea I agree ^^
I’d give it a chance. Will likely die off
