New to Reefing.....unwanted guests?

[Flo5777]

Hi All,
This is my 1st post, Ive learned a lot on here.
Have a 13G nano tank, been going for about 10 months. Home to 2 clownfish, One red striped angelfish, one red skunk cleaner shrimp, a few snails, some Zoas & today some extra critters.
While cleaning the tank I caught this worm thing, not sure if its a bristle worm, was about 1.5 inches long. 1st time Ive seen it? Additionally noticed these clear hard balls on the snail. Has it been breeding, are they eggs or something else.....they are nowhere else in tank.
Thanks for any advice or help!

The first one is a bristle worm. Harmless(as long as you don’t touch them with bare hands) and a good scavenger in my opinion. The second picture is bubble algae. Take it out and remove the bubbles carefully. Rinse it and put it back

Probably bubble algae on snail and you will want to remove snail
from tank and then remove from snail. As for the segmented worm, it seems to have much in common with the "usual" bristleworms seen in many reef tanks but I would remove to be safe.

I keep bristleworms in my tanks as an integral part of cuc.
