Neon Guppies are named for their neon-bright and vibrant coloration. Their colors pop under aquarium lighting, adding a lively and captivating element to the tank.
Neon Guppies are named for their bright, metallic colors, often in shades of electric blue, green, gold, or red. The shimmering scales reflect light beautifully, giving the fish a glowing, “neon” appearance. Males tend to be more vibrantly colored with longer fins, while females are larger but less intense in color.

Peaceful, active, best kept in groups
To bring out their intense neon coloration, feed them a high-quality staple diet along with live or frozen treats such as brine shrimp, bloodworms, and daphnia. Vegetables like blanched spinach or zucchini help maintain digestive health and enhance coloration. Offer small amounts 2–3 times per day.
Livebearer – females give birth to free-swimming fry every 4–6 weeks
Like all guppies, Neon Guppies are prolific breeders. Females can produce fry every 4–6 weeks, with brood sizes ranging from 20–60 fry depending on her size and health. Fry are independent from birth but are best protected in tanks with dense plant cover or in separate breeding/nursery tanks to avoid predation by adults.
Neon Guppies prefer clean, well-oxygenated water with stable parameters. Keep pH between 6.8 and 7.8, moderate to high hardness, and a temperature in the mid-to-upper 70s °F. Perform weekly 25–30% water changes to maintain water quality and prevent nitrate buildup.
Potential health concerns include fin rot, ich, and bacterial infections if water quality declines. They are generally hardy but can suffer stress if kept with aggressive or fin-nipping fish. Overfeeding can lead to swim bladder problems.
Peaceful
Neon Guppies are lively, peaceful, and extremely eye-catching due to their glowing metallic colors. They spend much of their day swimming actively, exploring plants, and socializing with tank mates. Males often display their colors in courtship dances, making them a constant source of movement and visual interest.
The Neon Guppy (Poecilia reticulata) is a selectively bred variety prized for its glowing metallic appearance. Originating from the wild guppies of South America, they have been bred worldwide for intense colors that shimmer under aquarium lighting. Peaceful and easy to breed, Neon Guppies are perfect for community aquariums with other small, non-aggressive species. They are prolific livebearers, capable of quickly populating a tank if conditions are favorable. Their vibrant colors show best when they are healthy, well-fed, and kept in clean, stable water. With their hardiness, beauty, and constant activity, Neon Guppies remain a favorite choice for both beginners and experienced fishkeepers.
