How do you stop fish eating their fry?

1. Separate fry from adults. One of the most direct ways to prevent fish from eating their fry is to physically separate the two groups. This can be done by using a breeder box, a net, or even a separate tank. This also prevents the adults from intimidating or harassing the fry, allowing the fry to grow and develop in a stress-free environment.

2. Provide adequate hiding spots for the fry. Fish instinctively seek cover to hide from predators, and fry are no exception. Creating plenty of hiding spots in the tank, such as plants, caves, or driftwood, will give fry a place to躲避adult fish.

3. Feed the adults regularly and adequately. Well-fed adult fish are less likely to prey on their fry. Make sure to feed the adults a high-quality diet and feed them at regular intervals to ensure they are not hungry.

4. Dither fish. Adding dither fish to the tank can also help deter adult fish from eating their fry. Dither fish are small, active fish that keep adult fish distracted and less likely to focus on the fry. Some popular dither fish species include zebra danios, white cloud minnows, and rummy nose tetras.

5. Remove the fry from the tank when they reach a larger size. As the fry grow, they become less vulnerable to predation. Once they reach a certain size, they can be safely added back to the main tank with the adults. The size at which fry can be safely added back to the main tank will vary depending on the species of fish.
