What is this???

[reefs4life]

Hey guys so I found this sort of slug in my tank today, have nooo clue where it came from because I haven't gotten anything new for a long long time, at least nothing that this thing could have been carried on. Is it good or bad?? That's my biggest concern

Dendrodoris nigra

I think it is a sponge eater but search the name and you'll find more info

Tagging along. I have one too. All black body with white tip ear thingies. Mine is only probably 1 inch long, but haven't seen him touching anything important besides grazing on rocks.

Take it out they multiply like crazy.chitron i think thats what they are called ill double check

I don't think they're chiton. I have a few of them and I think they're cute. Not really an aggressive multiplier lol. This is completely smooth, and no exoskeleton

Seems to be that dendrodoris nigra. He seems very peaceful not too worried about it and he must have been in there for a long long time because I haven't gotten any new rock in a while so he can't be that bad because I haven't noticed anything wrong with the tank.
