9 Months Update - (Saving Amano Larvae) NO filter, NO CO2, NO Ferts 5 Gallon Nano Tank

This is 9 months update. The fish are called Sparkling or Pygmy gourami. This was a crazy month. I lost my favorite shrimp of all time. Breeding Amano: Half of the water is tap water b/c I wanted to grow algae. Specifically brown diatoms. Top off and water changes were done using ro/di water. 10% water change every 3 days to remove surface protein. I used hydrometer and thermometer in one to just check the fluctuation in salinity and the temperature in real time due to evaporation b/c the tank is so small. Hydrometer/thermometer But real salinity is check with: Refractometer (automatic temperature compensation) I don’t know why the larvae only lived for 19 days. Maybe the temps were too high 26~28°C (79~82°F). Or maybe the salinity was off. ~33ppt. Or the water quality wasn’t good since the tank was so small and relied only on algae for water quality. The light was 14W daylight color single T5 fluorescent left on for
