Does anyone know what this is?

Nudibranch of some kind?

On the front glass in my tank.

That’s what I’m thinking but don’t know if it’s a good or bad one. I did add some aptausia eating ones a month ago but didn’t look like that.

I was thinking aptasia eating but they don’t typically just hitch hike in. I bet it’s that. They will breed in your tank.

my other experience with nudibranches is a zoa eating nudibranch I once found in my tank. They are easy to identify because they use the zoa’s
Color as camouflage so if munched on Rasta’s it looked like a Rasta-nudibranch. Luckily there was only one and I removed him. I would have kept him if it wasn’t for fear of them multiplying.

My Zoa’s/Palys look fine. Thanks for you reply. Much appreciated. BTW I was just looking at the Rastas.

I have some arriving today for a tank refresh so that’s what jumped into my mind. I’m guessing they aren’t cool anymore but they’re pretty and nostalgic. It’s funny because 10 years ago so many of these zoas were like $10 a frag or even free in most clubs and now I see a single head photoshopped to hell online and called “MNOP Rasta Space Wrecker ******* 3000” and they’re $150 for WYSIWYG.
Sorry. I’m old and tend to rant

If that's a Berghia it was roughed up and shed a lot of its cerata. They do this when threatened.

Yup! Lol. I remember when you got the whole colonies for under 100 of most anything. Times have changed for sure.
