What could this possibly be? Thanks

Saw this, this evening by luck I guess and quickly retrieved it out. What could it be? Should I be worried? Thanks

I get the feeling that this one is “SAFE.”

Otherwise it’s a worm but I forget which kind it is?

Looks like a baby bobbit worm, I used to have many of those in my tank when I started. But when you see one, big chance theres more. They reproduce by splitting in half

They are good bottom cleaners so I wouldn't see a reason to remove him but it will eventually try to eat any small fish you have when it grows bigger, big downside yeah. But dw theres also traps made for those big ones! Works as a charm

so I'd definitely suggest getting an Arrow crab, to keep it under control. he's like the pest control so if they come out of the rocks u got ur guard out there for em.

When I went to 450L I started with dead rock specifically to avoid them. But the longer ive been doing this the more I realized even how terrifying they can be, it cleans where I cant reach so its pretty beneficial to your tank. I probably have a few now due to them coming in the rocks with the corals... I better not see em though

They have small hairs that sting btw so dont touch it

I can't see the bristles or the head well enough to say for sure which kind it is, but my first thought would be either a Dorvilleid worm (this would have 4 tentacles on the head) or a Syllid worm (these have long, hair-like bristles) - either way, this isn't a Bobbit (Eunice aphroditois), but it is a Bristleworm/Polychaete (taxonomic class Polychaeta) of some kind.

The majority of bristleworms we get are harmless/beneficial CUC - they don't eat live fish, but they will eat dead fish/other dead critters (again, acting as CUC). A handful of very rare bristleworms (such as the infamous bobbit) do eat fish or other critters in our tanks, but they're definitely not common in the hobby.

Most bristleworms do, however, have sharp chaetae (the "bristles" of the bristleworm) that can poke you, so it's not generally a good idea to try and pick one up.


Generally speaking, the only reason people want to get rid of bristleworms is because they don't like how they look - most people recognize they're beneficial, so they keep them anyway.

Yes bristle! That it!! English is my third language haha (my bad) there's many names for those critters, apparently I switched them up. Thanks for correcting it^-^
