More baby brine shrimp questions!

[Karen B.]

Ziss hatchery, aquarium co op eggs, I follow Cory’s video.

I harvest between 24 and 36 hours.

When I put them in a small container after rincing them, some swims but most sinks to the bottom... why? Are they dead?

I would also like to know what are the black specs with the BBS

Thank you! I will get it eventually. It sucks to be the worst aquarist on earth!

So are they moving around in the hatcher just before you collect them? possibly too much air in the hatchery causing the bbs to bash around on the sides and each other leading to death. You want it to be just enough air to keep them from settling

Black spots are the egg shells from the shrimp.
