Studies have shown most adult fish can maintain activity at around .75% dry weight to gross weight at tropical temps (~78 F). For reference this would be approximately 3.5g a day per pound of fish. For growing fish you should feed 2-3% dry weight daily which would be around 9g/lb.
Personally I feed smaller fish 1-2 times daily and adult fish 6 days a week with 1 day of fasting.
