Bug invasion

[The_Skrimp]

I looked into my tank in the middle of the night last night with a flashlight and saw what had to be thousands of these little bugs crawling everywhere. They don’t look like copods. They have almost a teardrop shape. At first I thought they were baby snails till I realized that there were thousands of them.
The video shows some zoanthids because it’s easier to see them against the coral but they are literally on everything, not just my zoas.
None of my coral or fish have been showing any signs of distress and my substrate is looking a lot cleaner lately... I’m hoping someone can ID these things. Are they isopods? Are they the good kind or bad kind?

Thanks!

Can’t open the Image, can you directly post the pictures on you message?

Sorry about that. It's a video.

I uploaded it to youtube.

vid , not working try again

Could they be ostracods? That’s my best guess. They don’t look like amphipods for sure and they look too big to be copepods.
Maybe @KJ can help

Looks to be black bugs..
Can you try sucking one out with an airline hose?

I looked up ostracods and those definitely look like they might be it.
I'll try pulling one out of the tank and take a better picture.

Ostracods, good guys.

That's good news! Thanks so much for the ID. With that many in my tank it was either going to be good or really really bad.

Stop moving the camera and zoom in a little if you can. Interesting.

I just seen your second video. First time seeing those guys in 5 years.

Agree on ostracods and algae eaters and only out in low to no light.
