Making a grand entrance…

opcje binarne forbes The Celestial Pearl Danio, or Danio margaritatus as it’s known scientifically, made it’s grand entrance into the hobby in 2006. Whilst a relatively recent discovery, this fish has been subject to a lot of attention, not only for its dazzling looks either.

applicazione scommettere opzioni binarie First discovered and photographed by Kamphol Udomritthiruj, there was initially a lot of criticism regarding the images of this fish, many believing them to have been computer generated. Such criticism provoked a firm response from Kamphol Udomritthiruj who published further photographs of his discovery, not only silencing his critics but sparking a huge interest in the fish.

Sales of this fish were obviously very popular, you don’t need to examine its unique and vibrant appearance for long to work out why. The fish was in good supply at the time and its price relatively low due to the large numbers collected.

…before its price shot up a firework

binäre optionen erfahrungen Whilst demand for the Celestial Pearl Danio was still very high, supply fell drastically following an export ban in Myanmar in 2007, also known as Burma, the country where this fish was originally discovered. It was understood at the time that the species was being over collected to the point of near-extinction.

double red opciones binarias At the time there had been no discovery of any other Danio margaritatus populations, making a decision to ban exports seem like a rational step to take. Naturally the result of this was a huge increase in prices as a result of the extinction scare.

Introductions over, now here’s how to keep and breed the Celestial Pearl Danio

الخيارات الثنائية ديفيد اليومي Despite their hefty price tag, it can be rewarding keeping this species at home. They are easy to breed and fairly tolerant when it comes to water parameters. They also look very attractive when kept in a well-planted aquarium and their fully developed colouration is a perfect contrast to vibrant green foliage.

Appearance and sexual dimorphism

http://wearesettle.org/?separ=binary-options-software-reviews&678=e1 binary options software reviews A very nice looking fish: the body has a blue background, similar to that on the Zebra Danio, with bright pearls along the side. The fins are adorned with intense orange stripes.

strategia opzioni binarie a fine giornata When ready to breed, this colouration intensifies in the males with the abdomen turning orange as well. Females are less brightly coloured with the body a paler colour having less pearls along it’s side. The orange colouration isn’t so prominent either.

ثنائي الخيار بوت 2.0 مراجعة Neither males nor females of this species are very big. Females are slightly larger and have fatter abdomens than the males, however neither is likely to exceed 2cm.

Aquarium size and setup

الخيارات الثنائية شباك الصيد استراتيجية Whilst these fish do not generally exceed 2cm in length, they can be aggressive towards each other. For this reason you should keep them in a tank at least 10 gallons in volume, preferably larger. Generally Celestial Pearl Danios live in waters not much deeper than 30cm so a long yet shallow tank would be perfect.

migliori siti trading online opzioni binarie Despite their flamboyant appearance, it is important to know that these fish are actually quite skittish. They prefer heavily planted aquariums with natural décor that breaks up the lines of sight along the tank. Plants found in their natural habitat include Elodea, an easy to grow aquatic plant.
Lighting, fertiliser and co2 should be added in accordance with your plants’ needs. Filtration needn’t be too ferocious and an air-driven sponge filter should suffice in the majority of cases.

Water parameters and diet

Whilst tolerant of a wide variety of water parameters, the Celestial Pearl Danio does best in slightly alkaline water, close to 7.3, yet fairly soft too. It can accept a large temperature range as well – anything from 20 to 26°C.

When it comes to its diet, this fish isn’t a fussy bunny. It will accept most flake foods although it would be a good idea to grind the food between your fingers to make it smaller for them.

Like many small aquarium fish, the Celestial Pearl Danio will find small invertebrates to snack on as well as algae, though don’t expect it to control an algae problem.

Should you wish to breed this fish, I would highly recommend using live food such as Daphnia, white worms, micro worms or good old Artemia.

Compatibility

In the wild, this fish doesn’t coexist with a great number of species. It is a skittish fish that will remain hidden in the presence of larger

tankmates. It will be less timid and you’ll see more of this fish if you include other similarly sized or smaller species. The Celestial Pearl Danio should generally be kept in decent numbers in a tank. This divides aggression amongst the fish and assures it is harder for any single fish to be picked out as the weakest. When kept in large groups, this fish is less timid and displays better colour. A shoal of Celestial Pearl danios looks exceptionally impressive. They shouldn’t pose a threat to shrimp.

Breeding celestial Pearl Danio

Owing to the extinction scare, it has been suggested on numerous occasions that only those prepared to breed this species should buy them. This has a reasonable logic under the circumstances thought to be present at the time of the uncertainty surrounding the wild numbers of Danio margaritatus. It’s just as well that this fish isn’t particularly difficult to breed in an aquarium.

The Celestial Pearl Danio is an egg scatterer that deposits patches or 30 or so sticky eggs on the leaves of plants in its environment. Prior to spawning, males can occasionally be seen attempting to guard a plant or area of dense vegetation. Sparring can also take place between males, though certainly not to the same extent as more aggressive fish like Bettas.
In order to increase the chances of spawning, dense planting or wool mops can be added to the aquarium. Fish should be conditioned with a varied diet that includes live food prior to breeding. There doesn’t appear to be any seasonality to their breeding so no temperature changes are necessary. Eggs are, however, unlikely to hatch is the temperature if at the lower end of the scale.

It takes around 3 to 4 days for eggs to hatch into very small and dark-coloured fry. You may not spot the fry at first glance as they tend to spend most of their time at the bottom of the tank. You can expect to wait a further 3 days before the fry become free-swimming although a small number of eggs and fry may be eaten by rival males. They won’t reach adult size until they are at least 3 months old. As soon as you think about breeding your Celestial Pearl Danios, you need to make sure you have everything you need to feed the fry at each stage of their development. Infusoria and micro worm are both good for this. Algae and microscopic inverts are naturally present in the aquarium but worth supplementing with fry foods.

Should you wish to raise greater numbers of fry, it is highly recommended that you set up a separate tank for raising the fry. This needn’t be large, but well filtered using a gentle air-driven sponge filter.

Whilst it’s a shame that the Celestial Pearl Danio endured such a price hike, I would like to end this article on the prediction that ease of reproduction and popularity of this species will sustain its inclusion in the aquarium hobby for years to come, be it by amateur or commercial breeding projects.
