Guppy Care Guide
 
Guppies (Poecilia reticulata) are one of the most popular freshwater aquarium fish due to their bright colors, active nature, and ease of care. They're also livebearers, meaning they give birth to free-swimming fry, making them fascinating for breeding projects.

pH: 6.8–7.8
Hardness: 8–12 dGH
Ammonia/Nitrites: 0 ppm
Nitrates: < 40 ppm
Filtration:
Use a gentle filter like a sponge or internal filter; guppies don’t like strong currents.
Substrate & Décor:
Sand or fine gravel; add live or silk plants (e.g., Java moss, Anubias) and hiding spots to reduce stress.
Lighting:
8–12 hours of moderate light daily; useful for plant growth and maintaining a natural day-night cycle.

Common Problems:
Fin rot / fungal issues: Usually from poor water quality

Tip: Add a bit of aquarium salt (1 tsp per 5 gallons) to promote gill health and reduce stress (avoid if keeping snails).
 
Guppies are hardy, colorful, and a joy to watch. With the right setup and regular maintenance, they’ll thrive and potentially multiply — fast! Make sure to plan ahead if you’re keeping both males and females.
