ID Larvae that came in on cerith snails

[Monkeytank]

I got some cerith snails and while I was acclimating them, I noticed all these little red dots swimming around. Some of them seem to have hatched. I'm trying to figure out what they are. I don't think they are ceriths. There may be more than one kind of animal here. Any ideas?

Definitely odd! Never seen that before.

It looks like it is maybe at least two different animals. About a third of the way in from the left you can see what looks sort of like a fish larvae, then there are the red and clear versions of something else in the frame.

Unfortunately larvae is larvae and you probably won't know what they are until they're somewhat developed. It would be really interesting to grow them out and see!

They've been alive at room temperature with no aeration for about 10 hours. I added some live phyto and some rotifers to the container. I will add some aeration and see if they make it overnight.

Sweet. Good luck!

Yikes! Hope it turns out to be something good.

Mysis or some type of shrimp....

I'm thinking it's different pods, and shrimp. Can you take some out and put them in a container to get a better close up picture?

Whatever they were, none of them made it.

That was a zoomed in picture taken with a dedicated macro lens. Those great big lines you see in the photo are fine scratches in the acrylic of a plastic cup.
