Variety of Guppy · fancy

📍 South America

The "fancy" designation refers to selectively bred guppies with exaggerated fin shapes (veil, delta, halfmoon) and a wide variety of color strains, developed through generations of selective breeding. Males are strikingly colorful with flowing tails while females are larger and plainer; they are among the easiest livebearers to keep and breed, suitable for community tanks of 10+ gallons.

Care Guide

Diet

Fancy guppies are omnivorous and thrive on high-quality flake foods supplemented with small frozen foods like brine shrimp, daphnia, and bloodworms 2-3 times weekly. Feed small amounts once daily, only what they can consume in 2-3 minutes, as overfeeding degrades water quality. Occasional vegetable matter like blanched spinach supports digestive health.

Behavior

Fancy guppies are peaceful, active swimmers that spend most time in the upper water column, displaying their elaborate fins through constant movement. Males are highly social and often interact with each other through fin displays, while females are more reserved; males may harass females during breeding season. They are curious and interactive with their environment, making them engaging community fish.

Breeding

Fancy guppies breed readily in captivity without special conditioning, as they are livebearers that produce 20-50 fry every 4-6 weeks. Females can store sperm and produce multiple broods from a single mating, making population control important in established tanks. Fry are large enough to eat standard fry foods immediately and grow quickly in warm, well-fed conditions.

Common Diseases

Fin Rot

Symptoms

Fraying, discoloration, or deterioration of fin edges; often starts at tail tips and progresses toward body

Treatment

Perform 25% water changes every 2-3 days, improve water quality, and treat with aquarium salt (1 teaspoon per 5 gallons) or antibacterial medication if severe

Ich (Ichthyophthirius multifiliis)

Symptoms

White spots resembling salt grains on body and fins, rapid breathing, flashing against objects, lethargy

Treatment

Raise temperature gradually to 28-30°C (82-86°F), treat with aquarium salt or ich-specific medication, and perform daily 25% water changes for 10-14 days

Velvet Disease (Oodinium)

Symptoms

Fine golden or rust-colored dust on body, clamped fins, rapid gill movement, loss of appetite

Treatment

Increase aeration, treat with copper-based medication or aquarium salt, dim lighting to reduce stress, and maintain 28°C (82°F) temperature

Dropsy

Symptoms

Severe bloating, scales standing out like a pinecone, lethargy, loss of appetite, pale coloration

Treatment

Isolate affected fish, perform frequent water changes, treat with antibacterial medication, and provide high-quality food; prognosis is often poor if advanced
