Things You'll Need
- Metric scale
- Tilapia fish food
Instructions
Feed baby tilapia until they're 3 weeks old a powdered fish feed. Select a formula that contains 50 percent protein to support the fish's rapid growth. Start by feeding them 30 percent of their body weight in food daily. As they grow, decrease the grams of feed you give them. A tilapia that weighs 5 grams receives an amount equal to 6 percent of its body weight. A fish that weighs 20 grams gets 4 percent of its weight in food every day.
Feed older tilapia pellets with a diameter that ranges from 3/32 inch to 1/8 inch. According to the North Central Regional Aquaculture Center, tilapia differ from other fish species by continuing to prefer small food as adults. The center also recommends floating pellets to make it easy for you to note your fish's response to the feed.
Divide your fish's daily ration into eight to 10 equal portions to be given as separate meals throughout the day. Tilapia have small stomachs and they expend a lot of energy, requiring frequent feedings.
