I saw this on YouTube and got interested as I have brine shrimp eggs to feed to fish (Lampeye killifish and a Betta)
These ones :

Just thought I would mention it as it is way cheaper than buying them and you can just hatch a few, instead of buying a big bag of them. My propagator has a grow light over it, but I am sure it would work without it if the propagator was in a lighter area than mine is.
The video is worth a watch just to see this person's lovely home with houseplants everywhere
