We have hatcched some brine shrimp and we were wondering how do you grow them to adult size? Do they live in fresh water or salt water? What do you feed them?
They live in salt water but they're not picky about the salinity. Anywhere between 20ppt and 100ppt will work.
They eat just about anything that is powder sized, Rotifers, dried eggs, yeast, etc. A nutritious phytoplankton would be best.
If you are looking for an occasional treat for your fish they are fine but they really offer very little nutritional value (soaking in selcon or similar product helps). Seems like growing them is more work then they are worth.
