Hi all !!!
We traveled back across the world to better understand a different habitat of Australia. The island continent has a unique flora and fauna as well as some very attractive ecosystems.
This time we will see a biotope located in the Northern Territory. That is one of the most extensive national parks in the world, Kakadu, but our destiny is a little more humble.
Located north edge of the park, found another smaller, but no less interesting, Nitmiluk National Park.
One feature of this park are its canyons (Sickles as known here) that the geology of the area have been piercing the beds of streams and rivers flowing into the sea.
Also abundant waterfalls and waterfalls that create pools where many species of fish found.
The animals that inhabit this park are varied and some of them very dangerous as freshwater crocodile, apart from also found 206 birds, 44 native mammals, 78 reptiles, 3 turtles, frogs and 25 in point, 38 species fish.
The climate in this area of the world is extreme in both directions, distinguishes between a wet season and a dry season.
In the rainy in just three months an average rainfall of 1000mm, however, in the dry season the channels lose much of its wealth and many become dry completely is rercoge.
Temperatures also have extreme ranges in the dry season are common daytime temperatures of 35 ° C for the day, dropping to 25 at night.
During the dry season, however, daytime temperatures reach 30 ° C and at night drop sharply to 10 ° C.
Between December and March when the rains drench, influence monsoon storms cause overflows and floods.
Under these conditions we can not say that the selected biotope has an annual continuity.
The chosen river system, the Daly River has several interesting and quite popular species that live in different habitats.
Likewise in its bed are varied aquatic and riparian plants, highlighting the Vallisneria nana, which creates small meadows in the central parts and margins of rivers, providing shelter to turtles and fish.
The ground is composed of compacted sand, silt, leaves of Eucalyptus species growing on its banks, branches, trunks and rocky areas.
Water parameters are variable, the temperature can vary depending on the season between 21ºC and 29ºC and pH between 7-8.2.
Among the 38 species of fish in the Daly River Basin, we could highlight the following; Melanotaenia exquisite, Melanotaenia nigrans, Melanotaenia splendida, Pseudomugil gertrudae, Hypseleotris compressa or Ambassis agrammus.
The biotope chosen these meadows are Vallisneria nana, this plant supports so emerged the dry season, which is why the colony grows each year, reaching large areas within the channel.
These plants grow in their natural habitat on virtually any substrate and although he prefers sunny areas, but also grows in shady areas.
Around and between these meadows are selected species as well as fry and juveniles of other species.
To translate this into our aquarium opt for a decoration composed of the most extensive group of Vallisneria nana or similar as we can get.
The size of the aquarium if we maintain a diverse and stable community must be greater than 300 liters, as are lively swimmers Melanotaenia tireless will tour the aquarium.
The ground will be composed of substrate at the bottom, covered with sand, gravel or small pebbles. About the scatter them Eucalyptus leaves (previously cooked), Terminalia, Quercus and Fagus.
Some roots, with some stones create shelters liked by Eleotridae, they finished surrounded by new outbreaks of Vallisneria.
As we have seen the temperature is not a factor in this almost, if it is instead the pH range between 7-0 and 8.0.
The most recommended filtration is a powerful external filter as it is important to maintain good water quality, so you will not be difficult to get the reproduction of the species.
You can add some filters more, mechanical or biological process for maintaining low levels of harmful substances for our fish.
From lighting quality and not quantity depend on the proper growth of this plant, as we can not access the Australian sun, we must choose one of the various options available, T5, T8, LED or PL.
We will better understand the possible inhabitants for our aquarium biotope, I say possible because we can choose to enter all species or choose from some of them.
Vallisneria nana, our star in this production plant reaches a height of 20-30 cm. Its leaves have a width of 1 cm and requires lots of light or addition of Co2 for proper growth.

Melanotaenia exquisita, this striking rainbow fish reaches a maximum size of 8 cm, like swimming in open spaces and their distribution is limited to the northern territories in Australia.
The Melanotaenia nigrans with dark longitudinal line, create a contrast between other more colorful Melanotaenias.
It reaches a size of 10 cm and its peaceful behavior and being active swimmers, will be a constant point of attention.
Melanotaenia splendida has an attractive color, depending on the light glows, still a sight to see.
Reaches a size of 12 cm and other fish rainbow is peaceful and active.
Melanotaenia splendida australis may be the Melanotaenia the most striking color pattern of living in the Daly River, I leave it to the discretion of each.
Its size is barely 10 cm and its distribution is relatively wide in northern Australia.
Like other rainbow fish are continuous spawners and during the breeding season are capable of sunsets every day.
They feed on small organisms and invertebrates that capture both the surface and underwater.
Pseudomugil gertrudae, this small fish just 3 cm in size, effected an exhibition with other males and females in the breeding season is very interesting to observe.
Its distribution is rather limited in northern Australia and some New Guinea.
It can be found in very different habitats as they can be small streams, wetlands or streams flowing through the rainforest. In all near abundant vegetation and leaves or stems in the background.
A good option might be to mount an aquarium as described above, smaller and specific size for this species.
The beautiful Hypseleotris compressa, I always thought it a wronged species.
It has everything to be a much more popular species in aquariums, but is relatively rare to see in the aquaristik circuit.
It reaches a size of about 10 cm and its distribution is in northern Australia and southern New Guinea. It feeds on invertebrates, crustaceans and other small aquatic organisms.
Pacific intraspecific behavior, with its congeners claimed a small territory.
Its reproduction is possible and a challenge for the advanced amateur.
Without being a fish with a very attractive coloration, the Ambassis agrammus with semitransparent body and yellowfin, call our attention. It reaches a height of 7 cm and like to swim in groups but sometimes remain detained in the water column.
And with that little more to add except that if montais one Biotope Aquarium Prairie Daly River Vallisneria stay no disappointed and be the focal point in your room.
Likewise do not hesitate to ask any question and if ye have fallen here by chance, to encourage you to register in the forum, where every day we try to learn something new.
