Galaxy Rasbora: Care Guide For The Attractive Species From Hopong

The Galaxy Rasbora is a very bonny, plump petty fish that'south like shooting fish in a barrel to care for and makes a great addition to a nano tank or beginner aquarist'due south customs setup.

These attractive fish are known by several unlike names, and that tin crusade confusion when y'all're shopping for additions to your drove. In this guide, we give you the full lowdown on this unusual species, including care, the ideal tank weather condition for your pets, and how to breed the Milky way Rasbora.

Kickoff of all, allow'south detect out more about the identity of this fish of many names!

Mistaken identity

The Galaxy Rasbora has the scientific name, Danio margaritatus. Just you'll also see the species advertised for auction online and in fish stores past several other names, including:

Celestial Pearl Danio
Fireworks Rasbora
Chilli Rasbora
Microrasbora sp
Celestichthys margaritatus ("heavenly fish adorned with pearls")

Originally, the fish was named Celestichthys margaritatus, and the genus Celestichthys was created specifically for them. However, a few years later on, the fish was reclassified as a Danio species and was renamed the Danio margaritatus.

The fish'southward common name, Galaxy Rasbora, was coined past collectors who acquired the species before it was officially scientifically classified. Thanks to its small size, the fish was causeless to be a species of Rasbora, although it was later reclassified as a Danio. All the same, the fish'due south common proper noun has remained in pop use.

Origins

The Galaxy Rasbora is a small cyprinid fish that comes from merely ane location, a very small area close to Hopong to the east of Inle Lake in Burma.

This beautiful little fish remained undiscovered until 2006 when it rapidly became known as a popular specimen in the aquarium trade. The fish's small size, brilliant colors, and peaceable nature made it the ideal improver to many hobbyists' community tanks.

The Angelic Pearl Danio is an omnivore, feeding on found matter, insect larvae, and small-scale invertebrates. This cute Danio lives in the minor ponds that take been formed past the overflow from small springs or from seeping groundwater.

Endangered?

But half dozen months after the fish appeared for auction in the aquarium trade, the species had reportedly become so rare that collectors were but able to take a few dozen of the fish from its natural habitat each day. With captive-breeding of the species proving difficult, most all the specimens for auction were wild-caught, placing even more stress on the diminishing population.

The situation was farther exacerbated by the fact that the Galaxy Rasbora occupies very pocket-size pools, which were quickly being fished-off. However, wild Celestichthys margaritatus is a prolific breeder that spawns pretty much on a daily basis, so ponds that were assumed to be completely devoid of fish afterward turned out to be completely restocked just a few months later.

In 2007, the Myanmar government banned the exportation of the Galaxy Rasbora. Since so, the population has recovered locally around Hopong, and now the trade is supplied exclusively with captive-bred specimens.

At the time of writing, the Celestial Pearl Danio is listed on the IUCN Red List as "decreasing," although there is insufficient information to estimate the current populations.

Advent

The Milky way Rasbora is a small, plump, blunt-nosed fish that grows to measure between i and 1.5 inches in length.

Males take a bright-blue background trunk coloration and have brightly colored fins, whereas the females are a boring bluish-green. The male's caudal peduncle is higher than it is in females. The male's body is adorned with a sprinkling of tiny, pearly spots, its back is a statuary-green colour, and the female has a yellowish-white belly.

Both sexes have transparent gill covers that permit the vivid red color of the gills to smooth through.

With the exception of the pectoral fins, the male person fish's finnage has 2 black parallel lines with a bright cerise surface area between. In the female, the pattern is only present in the caudal and dorsal fins and only occasionally in the anal fin.

During breeding, the male's underbelly is red, and his flanks get darker and brighter and so that the pearly dots are even more than prominent. Females in breeding condition take a blackness anal spot.

As juveniles, the Celestial Pearl Danio has a striped pattern that gradually morphs into the pearly spotted markings of the adult fish.

Care guide

Milky way Rasboras are relatively easy to care for, and its small size ways that this fish doesn't crave a very large aquarium to exist happy and to thrive. That makes the species suitable for the new aquarist who may be looking for something a lilliputian different and more unusual than the tetras and danios that are ofttimes chosen for starter tanks.

Tank size

The Pearl Danio doesn't need a very big aquarium, making them ideal for nano tanks. Then, a ten-gallon tank or a nano aquarium would be perfectly acceptable for a small shoal of 6 to ten fish.

Notwithstanding, y'all must call back that if you want to introduce more specimens to your drove, you lot'll need more space. Every bit a full general rule of thumb, you should let i gallon of water per 1 inch of fish.

Aquarium setup

Celestial Pearl Danios alive in heavily vegetated ponds, so you'll need to provide enough of alive plants that offer lots of hiding places for these shy fish.

You should also include driftwood and pebbles in your tank ornamentation scheme to replicate the fish's natural habitat and brand them feel at home in a tank setting. That's extremely important, as all tropical fish species demand to experience secure and safe if they are to be free-from stress.

Stress is a major killer of tank-kept fish, as it weakens the fish's allowed system, leaving them open to disease. So, be sure to make your Pearl Danios feel every bit condom as possible by providing them with enough of thick planting.

The water temperature can be as depression as 65° Fahrenheit or as high as 80° Fahrenheit. However, it'due south preferable to keep the temperature somewhere in the low to mid-70s Fahrenheit. That's helpful if you lot want to proceed other species of tropical fish with your Celestial Pearl Danios, as it gives you more choice.

The ideal h2o pH range is six.5 to 7.v, and a h2o hardness of 1 to 5 dGH is preferred.

You'll need to carry out weekly fractional water changes of between 25% and xxx% to keep the water make clean and reduce the levels of ammonia, nitrites, and nitrates in the tank.

Diet and nutrition

The Milky way Rasbora is an omnivore, and they are pretty easy to please when information technology comes to feeding.

A staple nutrition of high-quality micro-pellets or flakes is fine, and y'all tin can include some frozen foods, such as bloodworms and brine shrimp. Live nutrient, including alkali shrimp and white worms, are also a nutrition-packed add-on to the Pearl Danio's nutrition or every bit an occasional care for.

Tankmates

These mannerly lilliputian tropical fish prefer a peaceful community aquarium or a species-specific tank. The Galaxy Rasbora is a very shy fish that is easily intimidated by big or very ambitious species, so cull tankmates that won't hassle or nifty their smaller companions.

The Pearl Danio is related to the Danio erythromicron and has near identical care requirements, so if you can get hold of a pocket-size school of these fish, they practise make expert tankmates. Both species are schooling fish, so a larger tank is best to accommodate their behavioral needs and minimum group sizes.

A large aquarium tin really be brought to life by shoals of Pearl Danios and Endler'southward livebearers, and you lot tin can also include other top-dwelling house species such as Pygmy Hatchetfish. Many owners study that their shy Rasbora group comes out to play more often when other schooling species are included in the community.

The addition of shrimp and snails helps to mix things up and add interest to the tank, and these industrious creatures can likewise brand a great make clean-up crew, eating algae, leftover food, and general detritus.

Breeding

The Galaxy Rasbora is an egg-layer that's quite easy to breed in captivity. If you have a species-only tank, yous can permit the fish to spawn naturally, although information technology's preferable to divide the eggs from the adult fish immediately afterward spawning is complete to foreclose them from eating the eggs.

The Pearl Danio scatters its eggs over spawning mops or moss clumps, so you tin can remove them to another tank and leave the adults in situ. Alternatively, prepare a separate breeding tank and replace the fish in the display tank once you see that the eggs have been deposited.

The fry mostly hatches within 48 to 36 hours. These tiny creatures demand an exceptionally small food source. If your tank is well-established and contains micro-organisms and greenish algae, that volition provide sufficient nutrition for the fry until they are larger.

The fry grows rapidly into adults over the next iii months or so. As the babies grow larger, they tin be fed micro-worms, high-quality flake, and baby brine shrimp.

Diseases

The Milky way Rasbora is a fairly robust species of fish, just they can exist vulnerable to two of the most common freshwater fish diseases, Ich, and Fin Rot.

Both of these are bacterial diseases that are acquired by exposure to stress and/or poor water conditions. And then, by keeping the h2o make clean and carrying out regular water changes, yous tin help to prevent outbreaks of disease.

Ich (White Spot Illness)

Ich is a parasitic disease that's acquired by the protozoan parasite, Ichthyophthirius multifiliis. The Ich parasite lives in virtually tropical aquariums, but information technology but becomes a problem when fish in the tank are weakened by other diseases, poor h2o quality, or stress.

Fish afflicted by Ich may appear lethargic, flick or rub themselves against objects within the tank, and develop a rash of tiny white spots across the body, gills, and fins. Luckily, White Spot Disease is easily treated. Begin past raising the tank water temperature to 82^o Fahrenheit for four days. At the same time, you lot need to dose the whole aquarium with an over-the-counter White Spot treatment.

Fin rot

Fin rot is caused past 1 of several bacteria, namely, Vibrio, Pseudomonas, or Aeromonas. Fin rot is very easy to treat, but if yous don't accost the problem, affected fish will eventually die.

In the early stages of the illness, the edges of the fins get discolored and faded on the edges. As the disease spreads, tiny areas of the fins die and fall away, leaving a raw, ragged border. Equally the condition progresses, the affected area becomes red, inflamed, and bloody, as the tissue is eaten abroad.

Fin rot tin be treated with a proprietary medication that you add to the aquarium h2o. Commonly, the condition clears up quickly, and the fish make a full recovery.

Now that the fish are produced in numbers by commercial breeding operations, their cost is relatively low at around $4 or $5 per fish. Sometimes, you can become a slightly lower price if you buy a group of fish. That said, yous volition pay more if you order your specimens from an online supplier, equally you'll need to pay shipping costs.

Last thoughts

If you have a customs tank or yous want a single-species nano tank, the Milky way Rasbora could be a good choice of fish for you lot. These pretty little fish are somewhat unusual, and they make a not bad culling to more ordinarily seen small community species, such as tetras and guppies.

The Celestial Pearl Danio is easy to care for, too, readily bachelor, and modestly priced, and so they're a wonderful choice for a beginner hobbyist. So, if yous're just starting out on your aquarist's journey, this beautiful, shy Danio could well be the perfect tropical fish for your aquarium.
