| Other Information: |
The salinity in the larvae tank was dropped slowly overnight from 1.025 to 1.020 rotifers from the salinity 1.015 were added the next morning. Greenwater was added along with the rotifers. I added rotifers every day until day 4 and then the rotifers were able to reproduce enough to supply the fry with a constant food supply. I added 50mL(reduced with water) of microalgae suppliment for every day until the clowns were 14 days old. |
