Brine shrimp

There's magnetic ones that Rich uses too since they're easier to decapsulate:

The ones I linked to have ~100% hatch rate and separation without magnets

Aiptasia LOVE live baby brine shrimp. If you have Aiptasia you don’t want, I don’t recommend feeding it.

I tried a bunch of ways of hatching them, the best by far was:

Ziss hatchery

Ziss Brine Shrimp Hatchery | Live Brine Shrimp for Feeding Baby Fish

Ziss makes the best brine shrimp hatchery on the market because of its strong, impact-resistant plastic and ability to run a heater and thermometer inside.

Aquarium Co-op eggs (these eggs specifically)

Brine Shrimp Eggs | Best Food for Fish Fry | Aquarium Co-Op

Grow fish fry big and healthy by feeding live baby brine shrimp. Our eggs have a high 90% hatch rate with easy separation. Add water, salt & air to hatch.

With a small heater like:

Amazon.com

Mini air pump. Light optional.

I agree! I love this hatchery! And their eggs are definitely a much higher quality than others I have tried.

So i bought some of these. I could not get them to stick to any magnets. I don't know if there is a special type. I used various magnets and nothing.
