What Is an Electric Blue Guppy?

The Electric Blue Guppy is a selectively bred variety of the Poecilia reticulata species, known for its vibrant, metallic blue coloration that often covers the entire body and tail. This coloration gives it a shimmering, electric-like appearance under aquarium lights.

Electric Blue Guppies are part of the guppy family, which originates from South America and has become one of the most popular freshwater fish species worldwide due to their easy care and prolific breeding.

Appearance and Characteristics

• Coloration: Brilliant metallic blue, often with varying hues depending on lighting and genetics.

• Size: Adult males reach about 1.5 to 2 inches (3.8 to 5 cm); females are slightly larger, around 2.5 inches (6.3 cm).

• Fins: Males typically display long, flowing caudal and dorsal fins. Females are less colorful but still attractive.

• Lifespan: Typically 2–3 years with proper care.

• Behavior: Peaceful, active, and curious; they do well in community tanks.

Tank Requirements

Minimum Tank Size

A 10-gallon tank is suitable for a small group of Electric Blue Guppies, though larger tanks (20 gallons or more) are better for stability and community setups.

Water Parameters

Electric Blue Guppies are hardy, but maintaining ideal water conditions ensures better health and more vibrant coloration.

• Temperature: 72–82°F (22–28°C)

• pH: 6.8–7.8

• Hardness: 8–12 dGH

• Ammonia/Nitrites: 0 ppm

• Nitrates: < 20 ppm

Filtration and Aeration

A gentle filter (like a sponge filter or hang-on-back unit with low flow) helps maintain water quality without stressing the guppies. Adequate aeration is also important.

Lighting

LED or full-spectrum lighting enhances their electric blue sheen. Ensure a consistent light cycle of 8–10 hours per day.

Substrate and Décor

• Use dark substrates like black sand or fine gravel to enhance their coloration.

• Provide plants (live or artificial), driftwood, and caves for hiding and breeding.

• Floating plants like duckweed or water lettuce provide shade and security.

Diet and Feeding

Electric Blue Guppies are omnivores, and a varied diet ensures their health and enhances their coloration.

Recommended Diet

• High-quality flake or pellet food as a staple.

• Live or frozen foods like daphnia, brine shrimp, bloodworms, and mosquito larvae for protein.

• Vegetables like blanched spinach, zucchini, or spirulina flakes for fiber.

Feeding Frequency

Feed 2–3 times per day, offering only what they can consume in 1–2 minutes to avoid overfeeding and water pollution.

Electric Blue Guppy Breeding Guide

One of the most exciting aspects of guppy care is their ease of breeding. Electric Blue Guppies are livebearers, meaning they give birth to free-swimming fry rather than laying eggs.

Breeding Setup

• A separate breeding tank (5–10 gallons) is ideal.

• Maintain warm water (78–80°F) and include fine-leaved plants or breeding boxes for fry protection.

Mating Behavior

• Males will chase females to initiate breeding.

• It’s best to keep a ratio of 1 male to 2–3 females to reduce stress on the females.

Gestation Period

• About 21–30 days.

• Females develop a dark gravid spot near the anal fin as pregnancy progresses.

Fry Care

• Separate fry from adults, as even parents may eat them.

• Feed infusoria, crushed flakes, or baby brine shrimp multiple times a day.

• Provide dense vegetation or floating plants for cover if fry are kept in a community tank.

Common Diseases and Health Concerns

Like other guppies, Electric Blue Guppies are susceptible to certain diseases if water quality or nutrition is poor.

Common Ailments

1. Ich (White Spot Disease) – Treated with temperature increase and Ich medication.

2. Fin Rot – Often due to poor water quality; treat with antibiotics.

3. Velvet Disease – A parasitic infection requiring medication.

4. Internal parasites – Signs include weight loss; use anti-parasitic treatments.

Preventative Measures

• Maintain stable, clean water conditions.

• Quarantine new fish before introducing them to the main tank.

• Avoid overfeeding and overcrowding.

Ideal Tank Mates for Electric Blue Guppies

Electric Blue Guppies are peaceful and do well with other non-aggressive community fish.

Compatible Tank Mates

• Neon Tetras

• Corydoras Catfish

• Mollies

• Platies

• Swordtails

• Cherry Shrimp

• Snails (Nerite, Mystery)

• Harlequin Rasboras

Tank Mates to Avoid

• Betta fish (some may be aggressive)

• Cichlids (e.g., Oscars, African species)

• Tiger Barbs (known fin nippers)

• Any large or aggressive fish

Tips for Enhancing Electric Blue Coloration

• Feed color-enhancing foods with astaxanthin and spirulina.

• Maintain clean water and optimal lighting.

• Avoid hybridizing with other guppies to preserve the Electric Blue trait.

• Choose high-quality breeding stock for the brightest hues.
