What is going on here?

I couldn’t sleep last night, so I went to check out the tank at night. To my surprise there was a cloud of tiny critters that looked like fry at first. Upon closer inspection, they have two eyes and a V shaped tail. They swim backward and look more like baby shrimp. I have 3 shrimp, but they’re different species.

Any thoughts?

Pretty likely mysid shrimp. I have a ton in my frag tanks

Do Mysid have that same jumping, herky-jerky movement that some species of pods do?

I haven’t seen mine jump, but those don’t look like pods I’ve seen.

Looks like the little ones my cleaner shrimps spawn off every other month.

Not sure that what you’re seeing is what you think it is. Cleaner larvae takes like 4 months to settle out is much understanding. Much more likely mysid shrimp.

I only have one cleaner, one peppermint and one banded coral. No pairs.

Agree that they don't look like copepods. My big question is how is it that they haven't all been eaten by now?

That’s what I thought at first but upon inspection they were coming from the belly of the cleaners. Same way that my freshwater shrimp spawned so it was a semi familiar sight.

I think I caught this right after they spawned because there was a cloud of them in the tank. Didn’t see any the next day.

Here’s another video:

Even though you have 3 different type of shrimp, have you ever noticed eggs attached to any of them?

Nope. We did get a Pom Pom crab that had eggs when she arrived.

I have seen these in my tank before. I think they were from cleaner shrimp or peppermint shrimp. Both carried eggs under their bellies. But as others have said, probably mysid.

any survivors still?
