Can harlequin rasboras and black skirt tetras platys guppies live together?

Yes, harlequin rasboras, black skirt tetras, platys, and guppies can live together in the same aquarium. These species are all peaceful and relatively easy to care for, making them suitable for a community tank. Here are some points to consider when keeping these fish together:

1. Water Parameters: Ensure that the water parameters are suitable for all the species involved. The ideal water conditions for these fish are as follows:

- Temperature: 72-82°F (22-28°C)

- pH: 6.5-8.0

- Hardness: 5-15 dGH

2. Tank Size: The tank should be large enough to comfortably accommodate all the fish. As a general rule, provide at least 1 gallon (3.8 liters) of water per inch of adult fish. For a community tank with these species, a 20-gallon (76-liter) tank would be a good starting point.

3. Filtration and Water Changes: A good filtration system is crucial to maintain the water quality in the tank. Regular water changes (10-25% per week) are also essential to remove waste and keep the water fresh and clean.

4. Hiding Places: Provide plenty of hiding places for the fish, such as plants, driftwood, and rocks. This will help them feel secure and reduce stress.

5. Temperament: All these species are generally peaceful and compatible, but observe them closely to ensure there are no signs of aggression or bullying.

6. Feeding: These fish have different dietary needs. Harlequin rasboras and black skirt tetras are omnivores and will accept a variety of foods, such as flake food, pellets, brine shrimp, and daphnia. Platies and guppies are livebearers and may need additional plant matter in their diet, such as algae wafers or blanched vegetables.

7. Breeding Considerations: If you plan on breeding any of these species, keep in mind that platies and guppies are prolific breeders and may overpopulate the tank quickly. To control their reproduction, you may need to separate them from other fish or remove the fry regularly.

8. Compatibility with Other Species: While these species are generally compatible with each other, further research is recommended if you plan to add other fish to the community tank. Always check for compatibility with the existing fish before introducing any new species.
