Setting Up The Fry Tank
Guppy fry need a safe and stable environment to grow. Setting up the fry tank properly helps them survive and thrive.
This guide covers tank size, water conditions, and essential equipment for fry care.
Choosing The Right Tank Size
Use a small tank for fry to make monitoring easier. A tank between 5 to 10 gallons is ideal. It provides enough space without wasting water.
- A 5-gallon tank is good for up to 20 fry.
- Choose a larger tank if you have more fry or want to add plants.
- Ensure the tank has a secure lid to prevent escapes.
Water Conditions For Fry
Keep water clean and stable to protect the delicate fry. Use a gentle filter to avoid strong currents. The temperature should stay between 74°F and 78°F (23°C to 26°C).
| Parameter | Recommended Range |
| Temperature | 74°F – 78°F (23°C – 26°C) |
| pH Level | 6.8 – 7.8 |
| Ammonia | 0 ppm |
| Nitrite | 0 ppm |
| Nitrate | < 20 ppm |
Essential Equipment
Use specific tools and gear to maintain the fry tank. These help keep the water clean and the fry safe.
- Small sponge filter to avoid strong currents.
- Heater to keep the water temperature steady.
- Thermometer to monitor temperature daily.
- Soft lighting to reduce stress on fry.
- Fine mesh net for handling fry gently.
- Water testing kit to check water quality regularly.
Feeding Baby Guppies
Feeding baby guppies properly helps them grow healthy and strong. Their tiny mouths need special food types.
Knowing what to feed and how often keeps fry safe and avoids tank problems.
Best Foods For Fry
Baby guppies need small, nutritious foods that are easy to eat. Choose foods that float or stay small in size.
- Infusoria or liquid fry food
- Crushed flake food
- Baby brine shrimp
- Microworms
- Powdered fry food
Feeding Frequency
Feed baby guppies small amounts often. This matches their fast growth and small stomach size.
| Age of Fry | Feedings per Day | Amount per Feeding |
| 1–7 days | 4 | Very small pinch |
| 8–14 days | 3 | Small pinch |
| 15+ days | 2 | Regular small feeding |
Avoiding Overfeeding
Overfeeding can harm baby guppies and pollute the water. Watch how much they eat and remove leftovers quickly.
Follow these tips to avoid overfeeding:
- Feed only what fry finish in 2 minutes
- Use a timer or schedule for feedings
- Clean tank regularly to remove waste
- Observe fry behavior for signs of hunger or fullness
Maintaining Water Quality
Good water quality is very important for guppy fry. Clean water helps them grow healthy and strong. Poor water can cause stress and illness.
Keep the water fresh and safe by checking it often. This keeps the fry happy and active.
Regular Water Changes
Change part of the water often to remove waste and toxins. This keeps the environment clean for the fry.
Use a siphon or a small cup to take out old water. Replace it with fresh, dechlorinated water at the same temperature.
- Change 20-30% of the water every week
- Use water conditioner to remove chlorine
- Match new water temperature to tank water
Monitoring Parameters
Test the water regularly to check for harmful chemicals. Keep ammonia, nitrite, and nitrate at safe levels.
Use simple test kits to measure water pH and hardness. Keep the pH between 6.8 and 7.8 for guppy fry.
- Ammonia should be 0 ppm
- Nitrite should be 0 ppm
- Nitrate should be below 20 ppm
- pH level between 6.8 and 7.8
Preventing Contaminants
Keep dirt, chemicals, and other harmful things out of the tank. Use clean tools and hands when working in the tank.
Avoid overfeeding the fry. Leftover food can pollute the water and harm the fish.
- Wash hands before touching the tank
- Do not use soaps or detergents near the tank
- Feed small amounts of food, remove leftovers
- Keep tank away from dust and sprays

Protecting Fry From Predators
Guppy fry are small and fragile. They need special care to survive in a tank.
Predators in the tank can easily eat the fry. You must protect them well.
Selecting Tank Mates
Choose tank mates that are peaceful and small. Avoid aggressive or large fish.
- Small tetras and rasboras are good choices.
- Avoid cichlids and large gouramis.
- Snails and shrimp do not harm fry.
- Keep only a few tank mates to reduce stress.
Using Hiding Spots
Fry need places to hide from predators. Plants and decorations help create shelters.
| Hiding Spot | Description |
| Live plants | Dense leaves provide good cover |
| Plastic plants | Safe and easy to clean |
| Small caves | Protect fry from open water |
| Floating plants | Reduce light and add shade |
Separating Fry When Needed
Sometimes separating fry is best. Use a breeding box or separate tank.
Benefits of separation:
- Protects fry from being eaten
- Allows easy feeding of small foods
- Monitors fry health closely
- Reduces stress from other fish
Promoting Healthy Growth
Guppy fry need special care to grow strong and healthy. Proper conditions help them develop well.
This guide covers key tips to support your guppy fry’s healthy growth. Focus on temperature, lighting, and stress signs.
Optimal Temperature Range
Keep the water temperature stable between 75°F and 82°F. This range helps fry stay active and eat well.
- Use a reliable aquarium heater
- Check temperature daily with a thermometer
- Avoid sudden temperature changes
- Keep tank away from drafts or direct sunlight
Lighting And Environment
Guppy fry need a calm environment with moderate lighting. Bright lights can stress them out.
| Lighting Condition | Duration per Day |
| Soft, indirect light | 8 to 10 hours |
| Dark period | 14 to 16 hours |
Provide hiding spots with plants or decorations. This helps fry feel safe and grow well.
Recognizing Signs Of Stress
Watch your guppy fry closely. Stress signs can slow growth and cause illness.
- Fry hiding more than usual
- Loss of appetite
- Unusual swimming patterns
- Faded colors or spots on the body
If you see these signs, check water quality and tank conditions. Fix problems quickly to keep fry healthy.
