1. Separate the Fry:
* Breeding Box: The safest option is to move the pregnant female to a breeding box (a small, screened container) a few days before she's due. This prevents the adults from eating the fry.
* Fry Tank: If you have a spare tank, setting up a separate fry tank is ideal. This provides more space for the fry to grow and less chance of overcrowding.
2. Provide a Suitable Environment:
* Water Parameters: Maintain stable water parameters: 72-78°F (22-26°C) temperature, low nitrates, and a pH of 6.5-7.5. Regular water changes are vital, especially in a breeding box.
* Aquascaping: Use plants, rocks, and caves to provide hiding spots for the fry. Java moss is great for hiding and offering food sources.
* Light: Keep the lighting dim to minimize stress for the fry.
3. Feed Them Right:
* Infusoria: Start with live food like infusoria (microscopic organisms) or microworms. These are small enough for the fry to eat.
* Baby Brine Shrimp: Gradually transition to baby brine shrimp, which are easy to culture at home.
* Flake Food: Once the fry grow larger, finely crushed flake food can be added to their diet.
* Feeding Frequency: Feed several times a day, as much as they can eat within a few minutes.
4. Keep an Eye on Water Quality:
* Water Changes: Do regular water changes, especially in a breeding box.
* Ammonia and Nitrites: Test for ammonia and nitrites regularly. These can build up quickly in a small space and harm the fry.
* Filtration: Use a sponge filter or an extremely gentle filter to avoid creating strong currents.
5. Monitor for Signs of Trouble:
* Fungal Infections: Keep a close eye on the fry for signs of fungal infections (white fuzz). If you see any, use a fungal treatment specifically designed for fry.
* Stress: Overcrowding, poor water quality, or being chased by larger fish can stress the fry, making them more susceptible to illness.
Additional Tips:
* Patience: Growing platy fry takes time. It can take several weeks for them to reach a size where they can eat regular flake food.
* Be Prepared to Thin Out: If you have a lot of fry, you may need to thin them out to avoid overcrowding. This can be done by gifting them to other aquarists or selling them.
* Safety First: Always wash your hands thoroughly before and after handling fry to prevent the spread of disease.
Remember, these are just general guidelines. Researching specific needs of your Mickey Mouse platy fry will ensure their optimal health and happiness.
