Gourami pearl. Paradox-hardy, unpretentious and prolific fish under threat!
Gurami pearl (Trichopodus leerii, orTrichogaster leerii earlier) - a bright representative of aquarium fish from Asia, or to be more precise, from Thailand, Malaysia, the Borneo Islands and Sumatra.
With great certainty we can say that pearl gourami is one of the most beautiful fish among its relatives, such as Honey gourami (Trichogaster chuna), Dwarf (Trichopsis pumila)Spotted (Trichopodus trichopterus)Kissing (Helostoma temminckii) and other species. Competition in beauty pearl gourami can make, except that Lelius (Trichogaster Lalius)with its unforgettable color variations.
In addition, pearl gourami is a very hardy, unpretentious and very prolific fish (depending on size, the female can produce up to 2000 eggs at a time).
And with all these qualities, this fish is marked by the International Union for the Conservation of Nature and Natural Resources (IUCH) as a species that could be threatened with extinction in the near future (Near Threatened (NT)). And the person is guilty in it, of course. And that's why!
Gourami pearl and “black water”.
In the wild, gourami live in swamps with the so-called “black water”. In color, it resembles slightly diluted coffee. Such water is very acidic (pH about 4.5). Yes, in aquariums, gourami get used to living in water with almost any parameters, but in the wild, if swamps with “black water” disappear, then gouras also disappear. And the marshes become less and less every year. In pursuit of profit, a man began to drain them and use them under plantations oil palmfrom which subsequently receive Palm oil. Therefore, to meet the sale of fish caught in the wild is now almost impossible. All of them are divorced and grown in aquariums.
Gourami pearl. Keeping in the aquarium.
When kept in home aquariums, this fish is ideal for beginner aquarists. She is very hardy, unpretentious and peaceful. Will be able to adapt to virtually any conditions of the content and parameters of the water in your tank. The only thing you need to consider is that gourami refers to a labyrinth fish, that is, it can breathe open air. Therefore, in the aquarium between the water and the aquarium cover should always be space with open air. And when transporting them, you cannot pump pure oxygen into bags, as is often practiced with other species of fishes. The labyrinth fish will immediately burn the internal organs.
Labyrinth - fish, accustomed to live in muddy, rich in organic matter and oxygen-free water. Due to this, they have formed a special organ - a labyrinth. This organ reminds a bag pierced with small blood capillaries. Thanks to them, the air ingested from the surface passes through the labyrinth organ and immediately enters the blood.
In terms of food, fish are also absolutely not demanding and will be happy to eat any food they offer: live, dry and frozen.
Gourami pearl. Interesting Facts.
- Due to the fact that pearl gourami in the wild live in “black water”, where vision doesn’t help much, their abdominal fins stretched into long and very sensitive antennas. With the help of which the fish constantly pluck the space around them. And this process is very interesting to watch. The main thing is not to settle aggressive fish with them, which will constantly tug on these antennae.
- Even fish can produce real sounds, especially during spawning. And what is the reason for this is not yet known.
- Gourami, like some other species, such as Striped Spray (Toxotes jaculatrix) can hunt surface insects. They are located near the surface of the water, look out for an insect sitting on a surface branch, then spit out a trickle of water, knock it down and eat it. True, in an aquarium this is almost impossible to see.
- And another very useful property of these fish. They are happy to eat hydra. And hydra is such a polyp that can grow from any small piece of itself, and therefore it is practically immortal and cannot be killed. And getting hydra out of the aquarium is far from easy.
A little bit about reproduction.
I myself have not yet set myself the goal of raising pearl gourami at our place, but judging by information from the Internet, this does not cause any particular difficulties. The only thing I will put here is the photograph of our male and female, so that you can easily learn to distinguish between them.
The male is much brighter colored, and his dorsal fin is much longer than that of the female. The female is paler, has no red abdomen and its fins are rounded.
In general, if you want to participate in the rescue of endangered species of animals and fish on our planet, feel free to start a pearl gourami. Perhaps in the future you will be able to breed them and thereby support and even increase the world population of these wonderful fish!
