Ah, the pearl gourami ! What a magnificent freshwater fish. Let me tell you about my experience with this captivating species. Having been a keen aquarist since I was 20, I was lucky enough to observe their reproduction at close quarters. It's a truly captivating spectacle! But before diving into the details, allow me to guide you through the essential aspects of the reproduction of pearl gourami.
Preparing the aquarium for breeding
To breed your pearl gouramis successfully, you first need to create the right environment. Believe me, I've learned the hard way that a poorly prepared tank can compromise the whole process!
Bin size and configuration
Start by choosing a dedicated aquarium of at least 50 to 90 litres. This is essential to give your future parents enough space. I personally opted for an 80-litre tank, and it works like a charm.
Water parameters
Pearl gouramis are a little fussy about water quality. Aim for a water temperature of between 28 and 30°C. The pH should be slightly acidic, between 5.5 and 7.5. Soft water is preferable. Don't forget to maintain a warm, humid atmosphere above the tank. A little professional tip: use a lid to keep the water warm.
Vegetation and décor
Vegetation plays a crucial role. Install a wide range of plants, especially floating ones like Riccia. These plants will provide support for the bubble nest. I've even used artificial plants while waiting for the real thing to grow, and it worked like a charm!
The pearl gourami breeding process
Now that your aquarium is ready, it's time for the show! Breeding pearl gourami is a veritable aquatic ballet. Let me take you through the key stages of this exciting process.
Building the bubble nest
The male is the master builder. He will build a nest of bubbles about 10 cm in diameter on the surface of the water. It's impressive to see him at work, blowing bubble after bubble with infinite patience. This nest will serve as a cradle for the eggs.
Mating and egg-laying
Once the nest is ready, the pair engage in a nuptial dance that can last up to 3 hours. It's a magical moment to watch. The female will lay between 500 and 1000 eggs. Be careful to remove the female after laying to prevent her eating the eggs. I made this mistake once, and believe me, I'll never do it again!
Hatching and first days of fry life
The eggs generally hatch after 2 to 3 days. The fry start to swim freely after 4 days. This is when the male should be removed. The formation of the labyrinth is a critical period for the young. Be vigilant and make sure that the atmosphere above the water remains humid.
| Step | Duration | Action |
|---|---|---|
| Building the nest | 1-2 days | Observing without intervening |
| Coupling | Up to 3 hours | Remove the female after |
| Hatching | 2-3 days | Monitor the temperature |
| Free swimming of fry | 4 days after hatching | Remove the male |
Care and feeding of fry
The survival of the fry depends largely on the care you give them. It's a delicate phase, but so rewarding! Here are a few tips to maximise their chances.
Adapted diet
At first, feed your fry infusoria. Then gradually switch to artemia nauplius. I've had excellent results by varying the diet. Here's an example of a feeding schedule:
- Days 1-3: Infusoria only
- Days 4-7: Mixture of infusoria and freshly hatched artemia nauplii
- After day 7 : Artemia Nauplius and powdered feed for fry
Water maintenance
Water quality is crucial for fry survival. Make small daily water changes, about 10% of the volume. Use water at the same temperature as the tank. I lost a whole litter once for neglecting this point, a lesson I will never forget.
Growth and development
Keep a close eye on the growth of your fry. The formation of the labyrinth is a key stage. Make sure that the atmosphere above the water remains humid to facilitate this process. It's interesting to watch them grow day by day!
Tips for successful reproduction
After years of experience, I've picked up a few tricks that make all the difference. Let me share them with you to increase your chances of success.
Selecting and conditioning broodstock
Choose healthy, well-nourished adults. Sexual dimorphism will help: males are more colourful with tapered fins, while females are rounder. Condition them with a rich and varied diet, including live or frozen food.
Timing and environment
Although breeding is possible all year round, I've noticed better results in the warmer months. Create a calm, stable environment. Avoid sudden changes that could stress your fish.
Breeding management in community aquariums
If you try breeding in a community aquarium, be aware that the survival rate of fry will be low. One tip: add plenty of floating plants to provide hiding places for the young. Personally, I prefer a dedicated tank to maximise the chances of success.
All in all, breeding pearl gourami is an exciting adventure. With patience, care and these few tips, you'll soon be able to watch your own fry grow up. Feel free to experiment and adapt these tips to your own situation. Every aquarium is unique, as is the experience you're about to have. Good luck with your breeding project!
