Setting Up A Fry Tank
Raising betta fry needs a calm and safe environment. Setting up a fry tank correctly helps baby fish grow strong.
This guide covers important tips to prepare your fry tank for betta fry survival.
Choosing The Right Tank Size
Small tanks work well for betta fry. A tank that holds 5 to 10 gallons is good for beginners.
Too large tanks make it hard to control water quality. Small tanks make cleaning easier.
- 5 to 10 gallons is ideal for 20-30 fry
- Use a tank with a secure lid to prevent jumping
- Keep tank location away from direct sunlight
Water Conditions And Parameters
Clean, warm water helps fry survive and grow. Keep water temperature between 78°F and 80°F.
Maintain a gentle water flow to avoid stressing the fry. Test water often to keep parameters stable.
- Temperature: 78°F to 80°F (25.5°C to 27°C)
- pH: Neutral to slightly acidic (6.5 to 7.0)
- Ammonia and nitrites: 0 ppm
- Nitrates: Below 20 ppm
Essential Equipment For Fry Care
Use gentle filters to keep water clean without harming fry. Sponge filters are best for fry tanks.
Provide soft lighting and hiding spots to reduce stress. Use a heater to keep water warm.
- Sponge filter for gentle water flow
- Aquarium heater with thermostat
- Soft LED or low-intensity lighting
- Live or artificial plants for hiding
- Small food suitable for fry like infusoria or baby brine shrimp

Feeding Betta Fry
Feeding betta fry is very important for their growth. They need the right foods in small amounts. Proper feeding helps them survive and grow strong.
Young bettas have tiny mouths and sensitive digestive systems. Giving them suitable food and feeding often supports their health.
Best First Foods
Choose foods that are easy to eat and digest. These foods help fry get energy and nutrients early on.
- Infusoria – tiny aquatic organisms perfect for the first days
- Baby brine shrimp – high in protein and easy to catch
- Microworms – small worms that fry can eat whole
- Liquid fry food – specially made for baby fish nutrition
- Crushed high-quality flakes – softened flakes for easier eating
Feeding Frequency And Amount
Feed betta fry small amounts many times a day. They need constant food but cannot eat too much at once.
| Age of Fry | Feeding Times per Day | Amount per Feeding |
| 1 to 7 days | 5 to 6 times | Pinhead-sized portions |
| 8 to 14 days | 4 to 5 times | Small pea-sized portions |
| 15 to 21 days | 3 to 4 times | Small pellet or flake pieces |
| After 21 days | 2 to 3 times | Regular fry food portions |
Avoiding Overfeeding
Overfeeding can harm fry health and pollute water. Watch their behavior to prevent feeding too much.
- Feed only what fry eat in 2 minutes
- Remove leftover food quickly
- Keep water clean by doing regular changes
- Watch fry for signs of bloating or slow movement
- Use a small spoon or pipette for precise feeding
Maintaining Water Quality
Keeping water clean is very important for betta fry to grow healthy. Good water quality prevents diseases and helps fry survive.
Regular care of the tank water creates a safe environment for the delicate fry.
Regular Water Changes
Change part of the water often to remove waste and keep water fresh. Avoid changing all the water at once to protect fry from stress.
- Change 20-30% of the water every 2-3 days
- Use treated water free of chlorine and heavy metals
- Match the new water temperature to the tank
- Remove uneaten food and debris before changing water
Filtration Options For Fry Tanks
Choose gentle filters that do not suck in or harm fry. Filters help keep water clean by removing dirt and toxins.
| Filter Type | Advantages | Considerations |
| Sponge Filter | Safe for fry, provides aeration | Needs air pump |
| Internal Filter | Easy to install, good water flow | Use guards to protect fry |
| Hang-on-back Filter | Effective filtration | Use pre-filters to avoid fry suction |
Monitoring Water Parameters
Test water often to keep the right conditions. Stable water parameters reduce stress and increase fry survival.
- Check temperature daily; ideal is 78-80°F (25-27°C)
- Measure pH; keep it between 6.5 and 7.5
- Test ammonia and nitrite; both should be 0 ppm
- Keep nitrate low, below 20 ppm
- Use reliable water testing kits

Preventing Common Diseases
Betta fry are delicate and need careful attention to stay healthy. Diseases can spread fast in small tanks.
Good care and early detection help prevent many common illnesses. Learn how to spot signs, isolate new fry, and treat safely.

| Check water quality daily | Prevent stress and infections |
| Observe fry closely | Spot illness early |
| Do not add food leftovers | Reduce bacteria growth |
Safe Treatment Methods
Use gentle treatments that do not harm fry. Avoid harsh chemicals and overdosing.
- Remove sick fry to a hospital tank

Encouraging Fry Growth
Betta fry need special care to grow strong and healthy. Small changes in their tank can make a big difference.
Providing the right environment helps fry avoid danger and grow faster. Here are some tips to help you support their growth.

Fry are very small and can get scared easily. They need places to hide from bigger fish and bright lights.
- Use live plants like Java moss or floating plants
- Add small caves or decorations with holes
- Place soft leaf litter on the bottom for cover
- Keep some dark corners in the tank
Managing Light And Temperature
Fry grow best with steady light and warm water. Sudden changes can harm them.
| Condition | Recommended Range |
| Light Duration | 8 to 10 hours per day |
| Water Temperature | 78°F to 80°F (25.5°C to 27°C) |
| Light Intensity | Soft, indirect light |
Avoiding Stress Factors
Stress stops fry from eating and growing well. Keep their tank calm and clean.
