I have been hatching out brine shrimp for a while now. I started using the soda pop bottle one and now have two hatcheries I got from this site:
Aquatic Eco-Systems: aquaculture, lake, koi pond and aquarium supplies
However, I am curious: since they hatch in salt, and we dump them into freshwater aquariums for the fish (marine does not count here), how long before the fresh water kills them? Since there is no mouth or anus, I think it would be osmosis that would do them in eventually, if they escape the fish.
Any ideas on this?
