Little crawling [emoji220] like critters

[MaMe]

I woke up yesterday morning to these all over the glass. Some look like they have one segment and others two. This is the best picture I have been able to get. It’s looking through a 6x magnifying glass. Any ideas?

Almost looks like baby snails, but I could be wrong.

Looks like flatworms, but not the planaria variety. How long has the tank been setup? I've heard of some showing up and then disappearing after the tank matures.

They look like common copepods. The ones with two segments actually are carrying eggs. They’re good live food and a good sign of a healthy tank. I think they’re Apocyclops but I’m not sure. Definitely a type of copepod though

The tank has been set up since March. They crawl around rather fast. They don’t move like a snail or anything.

I was thinking copepod but they are really tiny and my wrasse hasn’t been going after them.

Yeah copepods are really tiny, and amphipods are a bit bigger. I’m not too sure about the wrasse not eating them, but I have a scooter blenny who never picks off the glass, she only eats copepods off the rocks and sand. If you see your wrasse pecking at seemingly nothing, they’re going after a copepod.

those are copepods,

planaria or flatworms glide along slowly on glass. copepods swim or jerkily move and stop on glass. copepods are great for aquarium .
