Good or bad nudibranch

[jeffchapok]

Just saw this guy for the first time today. I've only added one frag since last November and it was really small, so I doubt he could have sneaked past me. So I have no idea how long he's been here.

Keep or get rid of him?

It's been in there a good while, and isn't causing you any issues then I would leave it.

I have to agree with the comment above, but I’m actually really curious what kind of nudibranch it is and what it eats - the coloration is beautiful.

Well they usually look like whatever they eat. If you have an corals that have that coloration and look like him then that's its food source and it'll eventually starve after it consumed the coral.

If not then it's eating something else of no importance in your tank and might just be a part of your invert crew.

I showed the pic and asked a very knowledgeable friend and he thinks it eats sponges.

It's better safe than sorry with anything unidentifiable

Ya I gotta agree, kill it or trade it in for some lfs credit, if it wasn't eaten in my tank and I found it....I woulda flushed it depending on the time.
