Try looking up bobbit worms :D
That’s a nice one to remind me of just before I head to bed....could be some fun dreams tonight! Probably the only aquatic creature not to feature in an episode of Octonauts (small child’s programme for those without small children).
240L: 6 cherry barbs, 2 honey gourami,
6 Otocinclus, 11 sterbai Cory, 6 standard rummynose, 4 golden rummynose tetra. But don’t quote me on that given how things are going!

57L: Ghost (Betta) & Pumpkin (nerite)

Parameters: gH2, kH1, pH7.6 (tap).

Fascinating things!

The nudibranch I mean, not that other thing that I'm trying to forget.

Had a read and a Google- whilst that article is pretty damning stuff, the one in your tank looks like it's from the berghia family which is at least one that is possible (maybe not probable) to keep with other living things

This is a berghia ( aiptasia eating nudi )

The spines on body are too long. Its a soft polyp eating nudi :P Look at the colour under blue lights. The tips are green ( the same as GSP/Zoas tend to be )
Image

Or if not then it could be a Eubranchus rupium

Image

Either way, its not a berghia and will most likely be munching on coral somewhere! take a look under the heads of coral or near the base. You might find egg sacks and/or more of them.

Maybe they were keeping the Bobbits for Prince Andrew's next visit to Woking? ;) :D

Some of the marine stuff is very obnoxious (or as I say "Burn the witches!").....

I really enjoyed keep marines for the random wildlife that you get. Yeah some of it is a bit scary to think about, but thats nature for you! One scary SOAB

Greetings from 🇨🇵 :] & welcome to AF-UK

If these are Berghia Nudibranch species they can be kept but with caution. I had two small white Nudibranch (species unknown) in my 130 gallon reef and yes they will eat Aiptasia but within six months I was inundated with them. With no Aiptasia left in my aquarium to eat, these Nudibranch start eating anything else that took their fancy, corals being on the top of their menu! :dodgy2:

They all disappeared after I added my Copperband Butterflyfish but this is no guarantee as a friend had one of these fish in his reef but his Copperband showed no interest in the Nudibranchs he had in his aquarium.

I have read that is believed that some Bristleworms species will attack these and consume them, but if that was the case I had very lazy worms. So few species will remove them that we can keep in a home reef aquarium and those that do, like a small reef octopus will eat just about everything else that you don't want consumed.

Word of warning, care is a must when handling these creatures as their toxins can cause irritation of the skin or worse.

Oh and Gentleman, if you get Bristleworm spines in the tips of your fingers, don't go to the toilet for a wee.... Trust me, you will regret it! :[
Boris has cancelled Christmas, great news, if your a Turkey.:dodgy2:

Fair enough - I was just approximating the shapes to Google images! Some of the other non berghia species look so different, I thought the similarities were pretty close (as a layperson).
