Additionally, it is crucial to consider the temperament of individual neon tetras when choosing tankmates for your molly fish. Some neon tetras may exhibit more predatory behavior than others, so observing their behavior and compatibility with molly fish is important before making a final decision. If aggression is observed, it may be necessary to separate the neon tetras from the molly fish to ensure the safety and well-being of the fry.

Choosing Suitable Tankmates for Molly Fry

When it comes to keeping molly fry in a community tank, selecting compatible tankmates is crucial for their survival and well-being. While mollies are generally peaceful, their fry can be vulnerable to predation from certain fish species. To ensure the safety and support the growth of your molly fry, it is important to choose suitable tankmates that will not view them as food.

Some ideal tankmates for molly fry include bottom-dwelling species like plecos and cory catfish. These fish tend to occupy the lower levels of the tank and are unlikely to pose a threat to the tiny fry. Additionally, other peaceful community fish such as platies, guppies, and some tetra species can coexist peacefully with molly fry.

It is important to research the compatibility and temperament of each potential tankmate before adding them to the aquarium. Consider factors such as size, feeding habits, and aggression levels. It is also advisable to provide ample hiding places, such as plants or decorations, to offer the fry a safe retreat in case of any aggression or territorial behavior from other fish.

Table: Compatible Tankmates for Molly Fry

Fish Species Compatibility
Plecos High
Cory Catfish High
Platies High
Guppies High
Tetra Species (e.g., Neon Tetras) Medium

By carefully selecting compatible tankmates for molly fry, you can create a harmonious community tank where the fry can thrive. Observing their interactions and ensuring a balanced environment will contribute to the overall health and well-being of your aquarium.

Creating a Conducive Environment for Molly Fry

Molly Fry

To ensure the survival and well-being of molly fry, it is crucial to create a nurturing environment in a separate nursery tank. This setup will provide the fry with the ideal conditions they need to grow and thrive. Here are some key factors to consider when setting up a nursery tank for molly fry:

Nursery Tank Setup

Start by selecting an appropriately sized tank for the number of fry you have. A tank with a capacity of 5 to 10 gallons should be sufficient. Ensure that the tank has a proper filter to maintain water quality and remove any waste or debris. A heater is also essential to maintain a consistent temperature between 75 to 80 degrees Fahrenheit, which is conducive to the fry’s growth.

In addition to the filter and heater, it is important to provide adequate aeration in the nursery tank. This can be achieved through the use of an air pump and air stone or a sponge filter. Proper aeration will ensure that there is sufficient oxygen in the water for the fry’s respiration.

Feeding Schedule

Molly fry have specific dietary needs depending on their age. It is essential to provide them with a varied and nutritious diet to promote healthy growth. When the fry are very young, they will primarily feed on infusoria, which are microscopic organisms that can be obtained by soaking plant matter in water or through commercially available liquid foods.

As the fry grow, you can start introducing them to baby brine shrimp, which provide essential proteins and nutrients. These can be obtained either live or frozen. Additionally, you can offer freeze-dried or frozen foods specifically designed for fry, such as daphnia or microworms. These foods should be provided in small, frequent feedings to ensure the fry receive adequate nutrition. As the fry mature, you can gradually introduce them to crushed flakes or pellets designed for young fish.

It is important to monitor the fry’s feeding habits and adjust the amount and frequency of feedings accordingly. Overfeeding can lead to poor water quality, while underfeeding can stunt the fry’s growth. Regular water testing and maintenance should also be conducted to ensure optimal conditions in the nursery tank.

Age Food
Newborn to 1 week Infusoria (obtained through soaking plant matter in water or liquid fry food)
1 to 2 weeks Baby brine shrimp (live or frozen)
2 to 4 weeks Freeze-dried or frozen foods such as daphnia or microworms
4 weeks onwards Crushed flakes or pellets for young fish

By following these guidelines and providing a conducive environment with the appropriate tank setup and feeding schedule, you can significantly increase the chances of molly fry survival and ensure their healthy development. Remember to regularly monitor water parameters, perform necessary maintenance, and provide appropriate care to give your molly fry the best start in life.


In conclusion, neon tetras have a high likelihood of eating molly fry, making them potentially incompatible tankmates. When selecting tankmates for molly fry, it is crucial to consider factors such as size, temperament, and feeding habits. By choosing compatible species, you can create a harmonious environment for the fry to thrive.

To increase the chances of survival for molly fry, it is recommended to set up a separate nursery tank. This dedicated space provides the fry with a safe haven away from potential predators. Additionally, establishing a conducive environment in the nursery tank, including proper filtration, heating, and aeration, is essential for the fry’s well-being.

Feeding the molly fry an appropriate diet based on their age is crucial for their growth and development. From infusoria and baby brine shrimp to freeze-dried/frozen foods, worms, and eventually flakes/pellets, providing a varied and nutritious diet will contribute to their overall health.

When creating a community tank with molly fry, it is vital to give careful consideration to the compatibility of species. By selecting peaceful and non-predatory tankmates, you can create a thriving ecosystem where the molly fry can grow and flourish. Remember, every decision made in the tank should prioritize the well-being and safety of the fry.
