Guppies as a Pet

Best in Show

A Guppy (Poecilia reticulata) is one of the world’s most popular freshwater aquarium fish – native to South America – Guppies are small -1 to 2 inches – peaceful – incredibly colourful – Guppies are “live bearers” – Guppies give birth to free-swimming fry – instead of laying eggs – Guppies are a favourite for beginner breeders.

 

1. Selective Guppie Breeding and Line Development

Best in Show Guppies

The foundation of a champion Guppy is good genetics – choose a Guppy fish that has:

• Straight, strong Guppy bodies
• Symmetrical Guppy fins
• Intense even Guppy coloration
• Consistent Guppy patterns
• Active confident Guppy swimming behavior
• No deformities or damaged fins on the Guppy

Many serious Guppy Breeders work with established show lines rather than mixed pet-store stock.

1. Start with the Best Stock Guppies:

• You cannot win with generic pet store guppies
• Acquire high-quality Guppy trios or Guppy pairs from reputable Guppy breeders

2. Separate the Guppy Sexes:

• Separate young males and females at the 3-week to 1-month mark – before they can breed
• To control Guppy genetics and prevent Guppy fin damage

3. Selective Guppy Breeding:
4. Only breed your largest most vibrant Guppy fish
5. Guppy with the thickest caudal peduncles
6. Guppy matching dorsal/caudal colors

Keep detailed records of your Guppy Breeding program.

 

2. Nutrition and Growth

 Frequent Guppy Feedings

• Grow-out Guppy juveniles need 4 to 6 small meals a day

2. Live Guppy Foods:

• Base your Guppy diet on newly hatched baby brine shrimp
• Base your Guppy diet on cultured daphnia
• Base your Guppy diet on micro-worms to maximize size and color intensity

3. Excellent Guppy foods include:

• Baby brine shrimp
• Daphnia
• Grindal worms
• High-quality guppy pellets
• Spirulina-based foods
• Foods containing natural color enhancers such as astaxanthin

Feed small portions two or three times daily to promote Guppy growth without polluting the aquarium.

 

3. Water Quality and Conditioning

1. Rigorous Guppy Water Changes:

• Perform 30% to 40% water changes weekly for Guppy juveniles
• Perform water changes up to 70% in Guppy Fry tanks
• Guppies thrive in scheduled – fresh – slightly hard water

 

2. Temperature Adjustment:

• Keep Guppy Fry tanks at around 27°C for rapid growth
• As show Guppy males mature into adults – 6 to 9 months – lower the temperature to 24-25°C – to slow growth – to preserve Guppy colors and lifespan

 

3. Guppy Tank Setup:
4. Use bare-bottom tanks -10 to 20 gallons
5. Guppy tanks painted black on the outside – bottoms – sides
6. This prevents Guppies from downward swimming
7. This action will make the Guppies colors pop

 

4. Train Your Guppy Show Fish

Experienced Guppy Breeders often keep potential Guppy champions individually for a short period before a show competition – this helps:

• Prevent Guppy Fin damage from tank mates
• Encourages full Guppy Fin extension
• Allows better Guppy conditioning
• Reduce Guppy stress on competition day

Some Guppy Breeders place mirrors near the tank briefly – to encourage males to display their fins – this should be done moderately to avoid Guppy show preparation exhaustion.

5. Prepare for Transportation

 Before travelling with your Show Guppy:

1. Do not feed your Guppy show fish for 24 hours before the Show
2. Use clean, oxygen-rich travel bags
3. Or oxygen-rich travel containers
4. Avoid Guppy temperature shocks
5. Keep your Show Guppy fish in darkness during transport to reduce stress.
6. Fasting your Show Guppy:

• Do not feed your Guppy show entries for 24 hours prior to bagging or benching
• This prevents waste buildup in the water – which causes dangerous ammonia spikes – and stress

3. Guppy Bagging and Transport:

• Double-bag your Guppy show fish,
• Ensuring plenty of airspace
• Pack the Guppy fish bags in a heavily insulated box
• If shipping your Guppy Show fish during early spring or fall – wrap heat packs in layers of newspaper – so they slowly and gently warm the bag – rather than overheating your Guppy Show fish

4. De-benching your Guppy Show Fish:

• Pay close attention to show de-benching regulations
• Pay close attention to show paperwork.
• Always get the Show Critiques from senior judges after the event
• To improve your Guppy lines for the next Best in Show competition

Many professional Guppy organizations recommend fasting your show Guppy before shipping – to keep the water clean during travel.

 

7. Understand Judging Standards

Most organizations evaluate:

Category	What Judges Want
Body	Straight, balanced, vigorous
Tail	Correct shape, full spread, symmetry
Dorsal Fin	Large, proportional, erect
Color	Deep, vivid, uniform
Pattern	Sharp and well-defined
Condition	Perfect health and active swimming
Overall Impression	Beauty, elegance, and harmony

International standards can vary slightly, but these principles are common worldwide.

8. Grooming on Show Day

Best in Show Guppies

On the day of the competition:

1. Inspect Guppy fins for damage
2. Remove any algae from Guppy display containers
3. Allow your Guppy fish time to settle before judging
4. Keep noise and Guppy handling to a minimum
5. Present only a Guppy fish in peak condition.

A calm, fully displaying Guppy often scores better than a stressed Guppy show fish with slightly superior Guppy genetics.

9. Family Tips for Young Competitors

Preparing for a guppy show is a wonderful family project

• Children can help with show Guppy feeding schedules
• Keep a notebook recording show Guppy growth and coloration
• Practice identifying the best Guppy specimens together
• Learn official judging standards as a family.

Treat competitions as learning experiences rather than simply trying to win – patience and careful Guppy breeding over several Guppy generations are usually what produces a Champion Best in Show Guppy.

Winning a Guppy Best in Show requires excellent genetics – careful conditioning – outstanding health -proper presentation – Judges typically look for body shape – fin symmetry –  colour intensity – vigour – how well the Show Guppy Fish matches the official standards for their Guppy class.
