Setting Up a Guppy Aquarium
1. Tank Size and Setup
- Tank Size: Minimum of 5 gallons for a small group, but 10 gallons or more is ideal for larger schools.
- Water Parameters:
- Temperature: 72°F–82°F (22°C–28°C)
- pH: 6.8–7.8
- Hardness: Moderately hard water is preferred.
- Substrate and Plants:
- Fine gravel or sand works well as a substrate.
- Add live plants like Java moss, Anubias, or Hornwort to provide hiding spots and enhance water quality.
2. Filtration and Lighting
- Use a gentle filter to maintain water quality without creating strong currents.
- Moderate lighting will showcase their vibrant colors and support plant growth.
Diet and Feeding
Guppies are omnivores and thrive on a diverse diet.
- Staple Foods: High-quality guppy flakes or micro pellets.
- Supplements: Include live or frozen foods like brine shrimp, daphnia, and bloodworms.
- Vegetables: Blanched spinach or zucchini as an occasional treat.
- Feeding Tips: Feed small amounts 2–3 times daily to prevent overfeeding and maintain water quality.
Behavior and Tankmates
1. Social Behavior
Guppies are schooling fish that feel more secure in groups of at least 5–6. They are highly active and often swim throughout all levels of the tank.
2. Compatible Tankmates
- Other peaceful species like neon tetras, mollies, platies, and Corydoras catfish.
- Avoid aggressive or fin-nipping fish like barbs or bettas.
Breeding Guppies
Guppies are livebearers, meaning they give birth to free-swimming fry.
- Breeding Tank: Use a separate tank with plenty of plants for fry to hide.
- Gestation Period: Around 21–30 days.
- Fry Care: Feed them finely crushed flakes or specialized fry food.
Tip: If you don’t want to breed guppies, consider keeping only one gender to prevent overpopulation.
