When can you put guppy fry into community aquarium?

It is generally recommended to wait at least 4-6 weeks before introducing guppy fry into a community aquarium. This allows them to grow large enough and strong enough to compete for food and avoid being eaten by larger fish.

Here are some factors to consider when deciding when to introduce guppy fry to a community aquarium:

1. Size of the fry: The fry should be at least 1/2 inch in length before they are introduced to the community aquarium. This will help ensure that they are not eaten by larger fish.

2. Community tank mates: The temperament and size of the other fish in the community aquarium should be taken into consideration. Some fish, such as larger cichlids or barbs, may be aggressive towards guppy fry.

3. Hiding places: The community aquarium should have plenty of hiding places for the fry to retreat to when they feel threatened. This can include plants, driftwood, or caves.

4. Food availability: The community aquarium should have an abundance of food available for the fry to eat. This can include live foods, such as brine shrimp or daphnia, as well as commercial fry food.

By following these guidelines, you can help ensure that your guppy fry are healthy and thriving when introduced to the community aquarium.
