Microscopic worms everywhere! Should I be worried?

How worried should I be about all of these worms in my sand bed??

This density of these critters is scary!!

You want an ecosystem, critters are good.

Dinophilid worm, probably a Dinophilus or Dimorphilus species - either way, they're harmless/beneficial:

Interstitial annelid about 1mm in length and among the tiniest animals. Good hitchhiker. Feeds on detritus, bacteria, protozoa, unicellular algae and diatoms.

Are you sure that these are not planaria that I need to somehow eradicate? They appear to be the reason my sand is also clumping…

Here is a clearer video of just one of them…note the two eyes and arrow shaped head.

100% yes. These are definitely Dinophilid worms.

100% yes. These are definitely Dinophilid worms.

Okay - so nothing to worry about. Thanks @ISpeakForTheSeas !

They look similar, but the difference is that dinophilid has a 6-7 segmented body whereas planaria’s silhouette is smooth. Yours is definitely segmented. I had this worry too some months ago.

it all makes sense now. These critters exploded in number in the tank due to the increasing diatoms population in the tank…which was triggered when I began dosing my tank with silicates to compete against dinos…

If it gets out of hand, I’ve realized API general will kill them off when I was treating my fish for other parasites. At the same time, I bet it’s just a phase. I still have them but I now only see one or two and I have to be searching really hard.

Thanks. Seen these around occasionally but had no good name and no good leads to start a search.
"Worm" encompasses like the vast majority of animal classification types on this planet.
So "some kind of worm" narrows down absolutely nothing, lol.

Alternative solution, give me your microscope, and you'll never have to know there is worms everywhere.

Haha, yeah, I find a lot of worms basically by chance - finding a kind that I'm totally unfamiliar with is often a lost cause otherwise.
