What are these?!

[wlmalek]

Out of curiosity I found these crowling only at this spot off the tank. They don’t look like pods or worms to my knowledge. What are they?

They move similar to microfauna like pods. But it's hard to tell without seeing a very close up image

Probably copepods or something similar. Hard to see details in the video.

I tried to zoom in but they are very small

Yeah, you would need a big macro camera setup. Probably nothing to worry about, just some harmless microfauna!

Took another video zoomed in. They appears like some kind off pods

Copepods or some sort of invert spawn.

Maybe ostracods? We had a thread a few days ago where hundreds appeared in somebody's tank, looked sort of like this except they were on the rocks.

That what I thought. The shocking to me is its an fish only tank. Dryrock, drysand every thing was qted with copper and dipped. It’s amazing how these things found a way to here.

I like these hoppy

Interesting, are they harmful? I never introduced anything other than fish and snails. And they all went through qt. Also, the setup is around 18 months old and they just appear after all that time.

wondering how did they manage to get in

Some off the non moving dots are actually snails egg. but, I don't think they are baby snails, aren’t they?

I don't think they're harmful. Should act like any other pod. As for how they got in, I suspect they came in on the snails if you didn't add any corals or live rock. If the snails can survive the treatment, so can any microfauna on them.

Looks like either copepods or amphipods, either way they are beneficial to a reef tank
