The well should have been tested before allowing it to be used for human consumption. Check the report for dissolved oxygen levels.
The recommended minimum dissolved O2 requirements are:
Cold water fish - 6mg/liter (70% saturation)
Tropical FW - 5mg/l (80% saturation)
Trop marine - 5.5mg/l (75% saturation)
You'll also need to check salinity, metals, pH, ammonia, and biological levels and determine if the levels are compatible with the species you wish to maintain. The well should be checked seasonally for the first 2-3 years to determine average levels (you WILL see seasonal differences).
