Cant find this critter on Google?

[Freestyler]

Hi Folks,
I posted an intro earlier and couldn't upload pics from my mobile so I am using my PC now. My setup is:-

1. 40G but I am in the UK so it's 150 Ltr to me,
2. 40lb of Caribbean live sand,
3. A nice centre piece of Aquaroche, and a small piece of live rock with coraline,
4. Eheim Pro 4 + 600 canister filter,
5. TMC Vectron 600 UV,
6. Eheim Stream On + 5000 power head
7. Todays addition of a Radion XR15 G4 + Reef Link which is a million times better than the 2 Eheim 12w daylight LED strips which came with the Tank.
8. Tank Eheim Vivalline150.
9. I have a pair of tank bred Clowns
10. 1x Royal Grammer,
11. 1x White stripe cleaner shrimp,
12. A Xenia on its own rock,
13. A brown & green Zoa colony,
14. 2 mushrooms close together on a frag but they seem to be pushing each other over, not sure if that's ok?

The build is 5 weeks old now and had the diatom bloom last week which cleared up after a couple of days. I used a bottle of JBL Denitrol 250ml live bacteria to start the cycle. The water parameters have been a bit up and down but nothing too drastic. PH was a bit low so added some Seachem Reef buffer and then the Nitrites were up which was resolved with a dose of Seachem Prime.
After fitting the new light I saw this Alien looking thing sucking on the glass so I googled it and found things close but not the same. While looking closely at the thing I then noticed the 100s of minute white things also on the glass. The tenticles are on its back as its mouth was stuck to the glass. Any help and advice will be greatly appreciated.

Alien Bug???

It's a nudibranch. Remove it.

a little off topic but your backing on the tank looks so weird haha is it a marble backing or something? I've never seen someone do that before gotta lets us know how it turns out I'm very interested to see how stuff grows on it

Good job I squashed it then after I fished it out. Eeek and thanks

lol idk if an eek squashing was needed 0o but Lions right it's some type of nudibranch which biggest issue they tend to be Very food specific and impossible to keep, so they just died with a few being a true negative to the tank. Only a few we know are safe and we can keep(even then with conditions) vs millions of other "wild" types.

No eek... cool critter. best part of reef keeping...the stuff you didnt know you had. (but do agree it had to come out)

The Backing is from Juwel its called Cliff light 3D its made out of stuff like expanded foam with a hard coating on it. It already has spots of coraline growing after 2 weeks

I agree there I have just seen some beautiful colorful ones after a quick search but that one was ugly.

Thanks for the HITCHHIKERS link it looks like an RODI dip for my Zoa is the way ahead.

For a dip, will distilled work as well or does it have to be RODI?

It worked fine. I think it's the same, just a another process of removing the TDS total dissolved solids. Reverse Osmosis/De-iornised from my LFS is done with a filter system but I didn't have any to hand.
