Brine shrimp hatch but don't swim


Recommended Posts

Has anyone had this happen?

Recently I've started hatching bring shrimp again and I'm getting a lot that hatch but just fall to the bottom.

Even while the hatchery was running it has a pile at the bottom.

Aquarium co-op eggs in a ziss hatchery. ~2T salt in 2L water. The light is just in for the picture.

Adult fish still eat them up but fry are less drawn to them because they aren't moving. There are still some in there swimming around but it seems like the majority is on the bottom

Did you run air stone in the hatchery?  If not maybe they didn't have enough air in the water?

Yep it has the full setup: airstone, heater, light (from adjacent tank)
