Live Bearing Aquarium Fish: A Comprehensive Guide to Care and Breeding

Introduction

Live bearing aquarium fish, unlike egg-laying species, give birth to fully developed young. This unique reproductive strategy has made them a popular choice among aquarists, accounting for 80% of the fish species kept in home aquariums.

Types of Live Bearing Fish

Live bearing fish belong to the order Cyprinodontiformes, which includes many familiar species such as:

• Guppies
• Swordtails
• Mollies
• Platies
• Wags

Characteristics of Live Bearers

Live bearers are typically small to medium-sized fish with vibrant colors and striking patterns. They reach sexual maturity at a young age, and females can produce multiple broods of fry throughout their lives.

Reproductive Characteristics:

• Females have a specialized organ called a gonopodium that fertilizes the eggs internally.
• Fry (baby fish) are born free-swimming and fully formed.
• Gestation periods vary between species, typically ranging from 21 to 60 days.

Water Parameters for Live Bearers

Live bearing fish require specific water conditions to thrive. The ideal parameters are:

Tank Setup for Live Bearers

• Tank Size: A tank of at least 10 gallons is recommended for a group of 6-8 live bearers.
• Filtration: A strong filter is essential to maintain water quality.
• Heater: Most live bearers require a heater to maintain a constant temperature.
• Live Plants: Live plants provide hiding places for fry and help maintain water quality.
• Decoration: Caves, rocks, and driftwood create a natural habitat for live bearers.

Feeding Live Bearers

Live bearers are omnivores that eat a variety of foods. A balanced diet includes:

• Flake food
• Frozen food (brine shrimp, daphnia)
• Live food (worms, insects)
• Vegetable matter (algae wafers, spirulina flakes)

Breeding Live Bearers

Live bearing fish are prolific breeders, and they can reproduce almost continuously under the right conditions.

Tips for Breeding Live Bearers:

• Provide a breeding tank with plenty of hiding places for fry.
• Use a gravel vacuum to remove dead fry and debris.
• Feed pregnant females a high-protein diet.
• Separate fry from parents once they are free-swimming.

Benefits of Keeping Live Bearers

• Easy to care for: Live bearers are generally hardy and undemanding fish.
• Beautiful and colorful: They add vibrant colors and patterns to home aquariums.
• Fast-breeding: They produce multiple broods of fry throughout their lives.
• Educational: They can teach children about the marvels of nature and the importance of responsible pet ownership.

Tips and Tricks for Live Bearer Care

• Check for ammonia and nitrite regularly. These chemicals can be harmful to fry.
• Perform regular water changes. This helps maintain water quality and prevents the buildup of waste products.
• Avoid overfeeding. Unconsumed food can decompose and pollute the water.
• Quarantine new fish. This prevents the introduction of diseases into the main tank.
• Provide plenty of hiding places. This reduces stress and aggression in live bearers.
