I Have Some New Creatures

[FlyJumper]

Apparently I noticed a very small bristle worm (2cm) in my 10g nano which is currently stocked with one clown goby. I've never experienced bristle worms.... if theres one are there usually more? Or any bad things I should know about these?

I also noticed umbrella like things attempting to swim around my tank, I saw two. Very small but clearly visible. Pest or pet?

Yeah you probably have several Bristleworms. They only bad thing you'll really need to know is that they can sting you so be careful handling your rocks.

anything about the other creature?

 

[chrissaysyes]

it's floating in the water column and it looks like an umbrella?

 

[FlyJumper]

yes and it seems like it tries to go to the top.

could be a hitchhiker jellyfish, is it too small to photograph?
