Then they can swim freely and feed. Juvenile tropical gars feed in the evening and primarily eat fish. They develop quickly, and after two years, they attain reproductive measurement.
Atractosteus tropicus is threatened by excessive ranges of overexploitation and alterations of its habitat. Distribution and populations have decreased significantly on account of these actions
