About Pearl Danio
Pearl Danios are small freshwater fish. They come from rivers and streams in Southeast Asia. They have shiny, pearl-like spots on their body. This gives them their name. Pearl Danios are also called Celestial Pearl Danios or Galaxy Rasboras.
These fish grow up to 1 inch (2.5 cm) long. They are calm and friendly. They do well in groups and like to swim together. This makes them great for community tanks.
Tank Setup for Pearl Danio
Setting up the right tank is very important for Pearl Danio care. They need clean water and enough space to swim.
| Tank Aspect | Recommendation |
|---|---|
| Tank Size | At least 10 gallons (38 liters) |
| Water Temperature | 22-26°C (72-79°F) |
| Water pH | 6.5 to 7.5 |
| Water Hardness | Soft to moderately hard (5-15 dGH) |

Pearl Danios like a planted tank. Plants give hiding places and make fish feel safe. You can add plants like Java moss, Anubias, or hornwort. These plants also help keep water clean.
Water Quality and Maintenance
Good water quality is key to Pearl Danio health. These fish do not like dirty water. Change 20-30% of water every week. Use a water conditioner to remove chlorine and harmful chemicals.
Keep the tank filter running all the time. A good filter cleans the water and provides oxygen. Do not use strong filters that create too much current. Pearl Danios prefer gentle water flow.
Feeding Pearl Danios
Pearl Danios are omnivores. They eat both plants and small animals. In the wild, they eat algae, small insects, and tiny water creatures.
In your tank, feed them a varied diet. This keeps them healthy and colorful.
- High-quality flake food
- Micro pellets
- Frozen or live brine shrimp
- Bloodworms (frozen or live)
- Algae wafers occasionally
Feed small amounts 2-3 times daily. Do not overfeed. Remove uneaten food after 5 minutes. This keeps water clean and fish healthy.
Tank Mates for Pearl Danios
Pearl Danios are peaceful fish. They do well with other small, calm fish. Avoid big or aggressive fish that may bully them.
Good tank mates include:
- Neon Tetras
- Corydoras Catfish
- Small Rasboras
- Small Shrimp
- Otocinclus Catfish
Keep Pearl Danios in groups of 6 or more. They feel safe and show natural behavior when in groups. A group also reduces stress and keeps the fish active.
Breeding Pearl Danios
Breeding Pearl Danios can be fun. They are egg scatterers. They lay eggs on plants or tank surfaces. The parents do not care for eggs. Sometimes, they eat the eggs too.
To breed Pearl Danios:
- Set up a separate breeding tank with soft water.
- Add fine-leaved plants or spawning mops.
- Feed the parents live or frozen foods to boost health.
- When eggs are laid, remove the parents to protect eggs.
- Keep water clean and stable during hatching.
Eggs hatch in about 2-3 days. Baby fish (fry) eat tiny food like infusoria or special fry food. Feed small amounts many times a day.
Common Problems and How to Avoid Them
Pearl Danios are hardy fish but can get sick if care is poor. Here are common issues and tips:
| Problem | Cause | Solution |
|---|---|---|
| Ich (White Spot Disease) | Poor water quality or new infected fish | Quarantine new fish, keep water clean, use medicine |
| Fin Rot | Dirty water, stress, or injury | Change water regularly, reduce stress, treat with antibiotics |
| Swim Bladder Issues | Overfeeding or bad diet | Feed smaller amounts, use high-quality food |
| Stress | Wrong tank mates, poor environment | Choose peaceful tank mates, provide hiding spots |
Keep an eye on your fish daily. Watch for changes in behavior or appearance. Early action can save your fish.
