macrostoma The Betta fish is a native and endemic to the north of the island of Borneo, particularly in the areas of Brunei, Sarawak and Mulu National Park. Belontiidae belongs to the family. Your name etymologically means Macro = Grande, Stoma = Boca. It is also known by common names such as Beauty Brunei (Brunei Beauty) or English moothbrooder Peacock (Peacock mouthbrooders). It is a fish in the wild reaches about 14 cm. The biotope inhabited courses consists of small streams of no great depth, where the ground is covered by a large number of leaves and branches that make it decomposes the water has a very acidic pH 4.5-5.5, with a temperature of 24-26 degrees.
is listed as vulnerable on the IUCN Red List of Threatened Species IUCN (International Union for Conservation of Nature and Natural Resources). Was collected for the first time by Regan in 1910 in two areas in the district of Labi in Brunei and Marudi in Sarawak, Malaysia, and was considered extinct for 50 years until in 1981 it was rediscovered in a waterfalls in Brunei Darussalam. The first imported into America in 1981 and became the first European in 1984.
Mu'izzaddin Waddaulah Hassanal Bolkiah, Sultan of Brunei, took a special interest in this fish and declared their protection in Brunei, have banned the capture and maintenance in captivity of Betta macrostoma in Brunei.
The fish, however, has been captured and bred in tanks by amateurs, and more commonly available for purchase from farmers in Thailand and Singapore. However, more serious hobbyists, and conservationists believe that, due to the precarious situation of the species, maintenance and breeding should be performed by experienced aquarists with an interest in perpetuating, rehabilitate, and study the species. Here you can see the wild and capture by Michael Lo at the border with Brunei.
The Betta Macrostoma is the fish most sought after and appreciated by any fan of wild bettas. Also known as the most difficult to maintain and obtain optimum conditions of water. You have to read a lot and a lot of information before embarking on the purchase of these fish, since apart from its delicacy is a kind quite, quite expensive, with no marketing in Spain. In fact I only know a gentleman in Murcia that remains.
For diseases in captivity, the species is prone to putrefaction of fins, which eventually kills the fish in two or three days, and may try it with the addition methylene blue and salt water aquarium. It is also susceptible to internal infections, and can be cured by adding to the previous solution oxytetracycline and doing daily water changes of 10%. They are also sensitive to a high rate of nitrates in the aquarium water.
On playback, I must say that we have a very interesting species both in courtship, in the very act of reproduction and hatching of eggs by the male. We recommend a couple in an aquarium of 60 liters or more, accompanied by some trees and plants where they can have enough slots and recesses. Must Close the caps of the aquarium, because these fish are specialized in jumping out of water. Be made to maintain the pH below 6 and are primarily fed with live food, based on shrimp (their main food in the wild), crickets, insects, worms, etc., But also may be fed with frozen food like shrimp or red larva. When conditions are favorable, the female will initiate breeding, you will notice that the female is ready to play when his side strips to become very dark, almost black, also obscures two points in the bottom of the mouth, as the tail fin and abdomen shrunken Fuller, also change the way you swim. The male will accentuate its red and black stripes of the tail fin and the operculum. This will approach the female with his body bent sideways and all the fins deployed after this courtship, the male will embrace the female body, characteristic of all the bettas. The female will begin to expel eggs that will be supported by the anal fin of the male that fertilizes the same time, once they are released, both will catch eggs in their mouth, those who take the female to the male will pass word of mouth .
After this process, the male incubate the eggs in her mouth for a period of 30-35 days without food, after these, the fry begin to emerge from his mouth with a size of 0.5-1 cm., which will be fed brine shrimp and microworms.
But that is another story, which I count on my own experiences.
