I just found this funny looking hitchhiker ,

Any thoughts on what it is?
When I touched it the neon green feather looking things fell off.

Keep it , or it might eat coral ?

Usually hitchhiking nudis are not good.

I'd ditch it. Berghia Nudibranchs are the only ones that I know of worth keeping, and they'll starve out without Aiptasia.

It's hard to tell with that pic. You may want to google lettuce sea slug. If that is it, they are algae eaters.

Looks like it could be a zoa eating nudibranch. I say tis because zoa eating nudis incorporate the zooxanthellae from their meal (zoanthids) into their own tissue, hence the neon green color. Plus the shape is correct for a zoa eating nudibranch.

Thanks, its gone.

Suggestion in how to get rid of all of them? I'm assuming there are more.
