I have seen this twice..it comes out for a few & disappears just as quick.

Some type of Nudibranch.
If you have any coral that looks like that thing odds are it eats them...
Many nudis look like what they eat..

It could be a fuzzy chiton. Pic is very blurry.

I was thinking chiton as well.. hairy chiton of some sort because all the others I saw look as if they have a hard shell..

So what about a sea mouse? Or is it more of a chiton?

I’ve had elephant slugs and nudibranch in my tanks. That looks like a nudibranch. Anything in the tank look like it? That’d most likely be what it is eating.

I have nothing in my tank that looks like this.. is it good or bad? Should I remove it?

looks like a nudabranch they usually eat anything that looks like them .
if you have nothing in your tank that looks like it it most likely hitched in
i'd play it safe and remove it

I agree .
However leaving it poses little threat besides when it dies from starvation.
If you keep an eye on it just pull it when it dies ..
Mine were purple/greenish and ate my GSP which is just what they looked like.
Mine hitch hiked in on the coral itself. They look so much like I never knew till they crawled off the coral.


Make sure it is not a Berghia before you remove it. They are good.. They feed on aptasia which no one wants anyways.

All nudibranch are specialized feeders. They will look like what they eat. Once it’s gone they will starve.
If you see one, there are eggs and you’ll see another even after you remove it.
I’d remove it either way.
