Here are the key aspects to pay attention to when caring for guppies:
Water Quality Management
Guppies thrive in water temperatures between 22-26°C (72-79°F), with temperature fluctuations ideally kept within 2°C (3.6°F). The tank water must be dechlorinated, which can be done by letting it sit still for 24 hours or using a dechlorination kit. Guppies prefer slightly alkaline water, with a pH level maintained between 6.8-8.0, and around 7.5 being optimal.

Feeding
Guppies are omnivorous, and their dietary needs vary by growth stage:
- Fry Stage (0-1 Month): Feed finely ground flake food or micro-pellet饲料 (pellets), 3-4 times a day in small portions, ensuring each meal is consumed quickly.
- Juvenile Stage (1-3 Months): Gradually introduce live foods like water fleas and brine shrimp, along with appropriately sized pellets. Aim for 2-3 feedings daily.
- Adult Stage (3+ Months): Offer a variety of appropriately sized foods, fed 1-2 times a day. Ensure they finish eating within a few minutes to avoid excess waste.
Breeding
Guppies are prolific breeders, but breeding management is crucial:
- After giving birth, immediately separate the mother from the fry to prevent cannibalism.
- Add plants like Java moss to the tank to provide natural breeding habitats and shelter for newborns.
- Perform regular partial water changes to maintain optimal conditions for breeding.
Disease Prevention
Guppies are sensitive to environmental changes and prone to illness. Key preventive measures include:
- Regular water changes (20-30% weekly) to maintain cleanliness.
- Avoid overfeeding, which pollutes water quality.
- Quarantine any sick fish immediately if symptoms like clamped fins, white spots, or loss of appetite appear, and treat with appropriate medications.
By focusing on these areas—water quality, balanced feeding, responsible breeding, and proactive health management—you can help your guppies thrive in a healthy, stable environment.
