#worm #hitchhiker

My reef is 4 mouths old. They have appeared out of nowhere and I'm not sure what to do. They are not copopods tho. What shall I do? I found hundreds in my tank and I tried removing them but i cant because there's so many... I need advice on what they are and how to deal with them, if they are...

My fiancé and I left for the holidays (about 2 1/2 weeks) and came back to find this really weird, thick white worm wriggling around on the floor of the aquarium. Granted, there’s a lot of algae build-up that’s being cleaned out today, but we’ve not seen anything like this worm before. Only...

HELP! I bought a 20 lb live rock that came with a bunch of mushrooms and than this morning at around 5:00 am so the lights were still off I saw this red and white creature come out looks almost like a caterpillar and has spikes....I tried to identify it but I can't seem to match the picture with...

So I buy my RODI water from my local Fish shop and today just before making my salt mix I poured the RO water into my mixing tub and noticed a few of these black worms in the water. Does anyone know what they are?

Got home to my gsp frag with all the polyps closes so I inspected and found these. Should I be worried? What are they?

I’ve been suctioning out multiple of these per day for a couple weeks now. Thought maybe bristle worms at first, then someone said maybe Medusa worms. I think these guys have legs, from what I’ve read Medusas don’t.

I have seen a few of these once in a while when I move a rock or something.. they look balled up and will roll across the sand.. I caught this one and googled it.. looks like a spaghetti or hair room.. any information would be great and if I should track all of them down I see and remove them...
