Wtf is this?!

[Empire]

Just saw this guy creeping on my rocks. I've never seen it in my tank before. My first reaction was to pull him out. Any idea? I can send you a video/more pics if this doesn't help and you are ok with me texting them to you. 7324916422

It's a nudibranch but that is the extent of what I know about them.

 

[redfishbluefish]

Black nudibranch.

 

[Empire]

Good bad?

 

[Empire]

It's black with white/gray dots. It's actually really cool

 

[redfishbluefish]

The little guy is a sponge eater.

 

[Empire]

Idc about sponge. Will he eat my corals?

 

[TanksNStuff]

Got a frag tank? Put him in there and see if he eats anything.

 

[Empire]

Not yet. I'm in the process of setting one up though.

Looks like a velvet nudibranch but I dont know if they come in that color ive seen one in blue. If it is, then it wont eat your coral.

 

[redfishbluefish]

They tend to be picky eaters, but I have white sponge that you're more then welcome to have to see if the little guy will eat it.

 

[Empire]

I bagged him up and let him float until I know for a fact he won't touch my corals. Paul, any idea if he will eat anything else? He's pretty big so if it wasn't a hitch hiker than he has been eating something. But I've never seen him before.

 

[redfishbluefish]

I'll stick with it being a Black Nudi after now looking it up.....HERE's my guess.

 

[MrsSmartyPants]

Now that you've established WHAT it is ... How big is that thing?

 

[Empire]

Maybe an inch?

 

[Empire]

Paul I think that's exactly what it is

[Empire]

Is it possible that it's a flatworm?

 

[redfishbluefish]

Some marine flatworms can take on a nudi appearance. However, flatworms are in a different phylum, while nudi's are in the mollusca phylum.....class gastropodes....same as snails and slugs. Is this thing flat or does it have some three dimension......that thing is nudi all the way.

That thing is cool!
