White caterpillar

[VVolfe]

Just saw this today. Maybe 1/2 inch in length. Seems to have two horns or antennae. Looks a lot like a caterpillar or slug.

Sorry for the terrible photo and video

Not the best pic (no offence) but by your description and the outline in the pic, nudibranch. Try to get a clear pic and someone may be able to tell you what it eats.

It finally is closer to the front where I could zoom up on it. Still not the best pic.

It's looking for food and probably going to die to starvation. I hope someone can id the guy.

It definitely is looking. It’s moving up the front glass this morning.

Poor thing. Sadly they are so picky. But, that's part of their job.

Nudibranchs usually resemble whatever they eat, so unless you have a coral in your tank that looks like that, the poor thing will starve.

From searching the web, the closest I have found is Dermatobranchus oculus.

Seems like they like to eat sea fans and sea pens, none of which I have.

I guess it is a bad thing to have in the tank.

Not a bad thing so much as a doomed thing. A bad thing would be something that eats your corals.

If you have any clove oil (which you should have on hand for emergency euthanasia of suffering fish), you should probably catch and euthanize it.
