During these days the couple behaved normally. When lean sideways next and curve their bodies, I think this may be signs of intimidation, intensifying the male and female colors darken their stripes.
I've been trying different foods, such as Ocean Nutrition Betta Food, which I accepted but not eager, red larva also frozen, like a lot. I have also tried to give them crickets, there is nothing like live food, devour them, and I also tested with live shrimp, and these are the ones they have drawn attention, quickly swam to eat.
ISI Quila massive flowering and their ecological consequences
Raulí Forest
increases in biomass of seedlings Raulí after the mass death of Quila.
For nearly 60 years culeou Chusquea (Quila, Colihue) a bamboo species dominated the forest understory of Nothofagus nervosa (= Alpine Raulí) in Argentina and Chile. However, in 2001 came a massive flowering event with subsequent death of Quila, affecting more than 200 thousand hectares. In this study, Marchesini et al studied forests located in the Parque Nacional Lanin (Neuquen, Argentina) to investigate whether micro-environmental conditions were substantially altered in the understory and explore its ecological effect both in the Quila as the regeneration of tree species. Examples of these changes are the increased availability of light in the understory, increased air temperature and soil changes in soil water availability. These changes could have an impact on the survival of seedlings of tree species. In this case, the authors explored the effects on Raulí, comparing sites with no flowering Quila (ie understory live) and flowering Quila (understory dead.) The authors found only an increase in light availability in the soil but found no changes in other microenvironmental variables studied. The establishment of Quila after flowering occurred in a small window of time (3 years) and Quila mortality showed no difference related to understory light availability. The death of quila led to an increase in survival, biomass, height and number of leaves and buds of the seedlings of N. alpina. This would suggest that the flowering of the Quila could generate microenvironmental changes that would influence the growth and survival of forest regeneration. The authors stress the need to conduct long-term studies would further clarify the ecological role of these extraordinary events and rare (may occur every 15 years) in the temperate rainforests of South America.

The wait has been interminable, but finally the day has come where I get my pair of Betta macrostoma. I have been a surprise because I expected that copies would measure about 4 cm. but the male is about 7 cm. and the female about 6 to 6.5 cm.
come individually bagged with Indian Almond leaves, and water probably a little tainted by the almond leaves. We have measured the parameters that bring water and are quite similar to the aquarium I have them prepared, a pH of 6.5 and a very low hardness.
The aquarium I have them preparation is an aquarium of 96 liters, naked, only a trunk and a loose ground. Filtration sponges and turf plate. Osmosis water, with added phosphoric acid to lower the pH.
I have acclimated and added water to the bag slowly, I later released. Apparently all is well. And let them rest until tomorrow.
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.
The Betta macrostoma market in Spain is almost nil because of the rarity, sensitivity and high cost of this fish, so that their imports from the stores of fish is very low or nonexistent. Since I was young, I've had aquariums most diverse biotopes, from cold water fish reef aquariums. Recently I had the opportunity to buy a pair of Betta macrostoma and not refused by it, because I encouraged the challenge of trying to maintain and reproduce a species that I find quite interesting. With this blog I intend to give a little information (low in English), collected from many websites and internet forums, as well as to inform the development of my partner and possible replication.
