- Size average 4 to 5 cm, ideal for medium aquariums
- Breathing labyrinthine can breathe atmospheric air
- Prefers water mild and slightly acidicbetween 22 and 28°C
- Enjoys an environment rich in vegetation
- Fascinating reproduction with building a nest of bubbles
Ah, the dwarf gourami ! This little freshwater fish has always fascinated me. Native to South-East Asia, it brings a touch of the exotic to our aquariums. Let me share with you my knowledge and experience of this captivating species. After all, I've been a keen aquarist since I started out in the pet trade, and have had the opportunity to observe and breed many specimens.
Discovery of the dwarf gourami: an aquatic jewel
Le dwarf gouramiknown scientifically as Trichogaster lalius, is a real jewel in the aquarium world. Its oval, laterally compressed body gives it an elegant silhouette that never fails to catch the eye. But its real charm lies in its colourful coat!
In wild specimens, there is an interesting alternation of red and blue vertical lines. I've always been impressed by this interplay of colours, reminiscent of an abstract painting. And believe me, when the light from the aquarium plays on their scales, it's a real spectacle!
Let's talk a little about its measurements. The dwarf gourami is, as its name suggests, rather small. On average it measures between 4 and 5 cm, with a maximum of 6 cm for the luckiest of fish. It's ideal for medium-sized aquariums, but don't underestimate it!
A fish with distant origins
Native to South-East Asia, the dwarf gourami is found mainly in the fresh waters of India, Pakistan and Bangladesh. These tropical climates have shaped its habitat requirements. In the wild, it frequents calm, vegetation-rich waters such as rice paddies, ponds and small streams.
A surprising respiratory characteristic
An exciting feature of the dwarf gourami is its labyrinthine breathing ability. This means that they can breathe atmospheric air as well as oxygen dissolved in the water. I have often watched these fish rise to the surface to take a 'breath of air'. It's an amusing sight that never fails to intrigue visitors to the pet shop!
Aquarium maintenance: creating a little aquatic paradise
For your dwarf gourami to flourish, it's vital to recreate an environment that's as close as possible to its natural habitat. Here are a few tips to help you achieve this:
Water parameters: the key to well-being
The dwarf gourami likes soft, slightly acidic water. Here is a small table summarising the ideal parameters:
| Parameter | Recommended value |
|---|---|
| Minimum volume | 80 litres |
| Temperature | 22-28°C |
| pH | 6,5-7,0 |
| Hardness | 1-10 GH |
Beware, these little fish are quite sensitive to sudden changes in parameters and to chemicals. I learned the hard way that a simple change of water can stress them. So be careful and proceed in small steps!
Aquarium layout: think plants
The dwarf gourami loves to wriggle between aquatic plants. An environment rich in vegetation will provide it with :
- Hiding places to feel safe
- Shady places to rest
- Support for the construction of the bubble nest during reproduction
Don't hesitate to vary the plant species: vallisnerias, cryptocorynes or hygrophiles will do the trick. I've always been partial to aquatic mosses, which give a natural look and provide excellent shelter for fry.
Social life and reproduction: an exciting world
The dwarf gourami is an interesting fish to observe. Although generally peaceful, it can be slightly territorial, especially during the breeding season. That's when the show really begins!
Living together: choosing the right companions
In my experience, dwarf gourami get on well with other calm species of similar size. I've had good results associating them with Corydorasand Rasboras or capercaillie. On the other hand, avoid species that are too lively or aggressive, which could stress them.
One piece of advice I often give: observe the behaviour of your fish carefully when introducing new companions. Each individual has its own personality and incompatibilities can sometimes arise.
The nuptial dance: an aquatic ballet
The reproduction of the dwarf gourami is a real spectacle! The male, who is more colourful than the female, builds a nest of bubbles on the surface of the water. He uses his saliva to create these bubbles, which is captivating to watch. He then parades around the female, spreading his fins in a hypnotic nuptial dance.
Once the eggs have been laid (50 to 200), it is the male that takes care of the eggs and fry. He protects them fiercely, even chasing the female away. I've always found the paternal instinct so well developed in this species touching.
Breeding championships and awards
Raising dwarf gouramis can be both rewarding and tricky. Unfortunately, these little fish are quite fragile and often fall victim to disease in the aquarium. I've learned the hard way that constant monitoring is necessary.
On the other hand, seeing them flourish in a well-tended environment is a real reward. Their average lifespan of 2 to 3 years may seem short, but every moment spent watching them is a renewed pleasure.
In summary, I would say that the dwarf gourami is a captivating fish that deserves our full attention. Although I often advise against them for beginners because of their fragility, they remain a popular choice for experienced aquarists. With the right care and a little patience, you'll have the joy of seeing these colourful little gems enliven your aquarium for years to come.
Remember, each fish is unique and adds its own touch of magic to our aquatic passion. Take the time to observe, learn and, above all, marvel at the beauty of aquatic nature.
