Swordtail Fish Diet

The diet of swordtail fish includes plant matter, small invertebrates, spirulina flakes, small insects, lettuce, daphnia, algae, and brine shrimp. Furthermore, these aquatic creatures need a protein-rich diet, which can be obtained from fish flakes or pellets. Additionally, they enjoy feasting on live food, such as mosquito larvae or bloodworms.
