Rasbora axelrodii – features, types and rules for keeping fish

Aquarium enthusiasts often choose Rasbora axelrodii, also known as the Axelrod rasbora. These little, vibrant fish are well-known for their eye-catching looks and calm disposition, which makes them an ideal addition to community aquariums.

Even though they’re fairly simple to care for, there are a few requirements and circumstances that must be met for them to flourish. Having a thorough understanding of the various Rasbora axelrodii species and their distinctive traits will enable you to provide the best possible habitat for them.

This post will go over the salient characteristics of Rasbora axelrodii, talk about the different varieties that are available, and offer crucial advice on how to maintain these fish in good health and happiness in your aquarium.

Habitat and features of life in the natural environment

Fish from small reservoirs in Southeast Asia called Rasbora axelrodii are distinguished by increased turbidity and acidification as a result of peat contaminants and the predominance of residual rocks. They decide to swim in the middle of the water since it warms up nicely there.

When a natural biotope experiences significant rainfall, the water’s parameters change, and they respond very negatively to these changes.

This species of fish cannot withstand the current. Water with even slight variations can be harmful, leading to frequent illnesses and early death.

Although Rasbora Axelrodii is a schooling fish, it does not create a distinct wedge shape. Although everyone at the school sticks together, they all have the freedom to do as they please, regardless of what other people think. It is noteworthy that my greatest comfort zone is a school of rasboras.

If you keep a few or four fish in an aquarium, they will hide in the thick underbrush near the bottom because they are afraid of water flow. To ensure that every fish feels as at ease and natural as possible, experts advise keeping this kind of aquarium fish in groups of at least ten fish.

Appearance and distinctive features

The fish are adored for their unusual look, which includes a translucent tail section and bright neon-colored scales in the dorsal fin region. Depending on the state of maintenance, the color may change.

In bright light, the female’s body is more translucent, while the males have brighter scales. The scales’ color shifts from neon blue to neon reddish-orange.

Another characteristic that sets females apart is the lack of a black border around the anal fin. The body’s slightly rounded abdomen is a result of spawning-related anatomical features.

Fish under stress turn translucent and lose their vibrant color. High alkali content, inappropriate water quality is the primary source of stress.

The fire rasbora, also known as Rasbora axelrodii, is a colorful small fish that livens up any aquarium. These fish, which are well-known for their tranquil disposition, are ideal for novice and expert aquarists alike since they are easy to care for and flourish in schools. This article examines the salient characteristics of Rasbora axelrodii, the various varieties that make up this species, and crucial pointers for setting up the perfect habitat that will ensure their happiness and well-being.

Features of maintenance

For aquarists who are new to the hobby, Rasbora Axelrodii is not advised, even though it requires modest maintenance and breeding. This is due to a number of very objective factors.

First, the water must be slightly murky and acidic for the fish to thrive, which is accomplished by adding unique chemicals that neutralize alkali. The color of peat water will not appeal to every breeder.

Second, in their natural habitat, Axelrods are only at ease in reservoirs with still water. They cannot withstand the current.

Thirdly, they have a hard time locating "neighbors" in the aquarium. Even though they are calm creatures, the fish nevertheless require particular circumstances that aren’t appropriate for all common aquarium fish species.

In light of these facts, Rasbora Axelrodii necessitates the proper creation of ideal living conditions in order to be maintained, specifically:

  1. Choosing an aquarium – the fish are extremely active, so they love shallow, narrow and elongated aquariums, a mandatory condition for which is the presence of a top cover. If it is not there, then on the first night half of the flock will make an attempt escape by jumping out of the aquarium.
  2. Water parameters – it is best to take measurements daily, as the parameters may change, causing stress in the fish. Water should be changed once a week, draining ¼ of the total volume. When adding water, agents that reduce the concentration of alkali are first added to it.
  3. Lighting– diffused light is required, as well as partial shade, which is formed with the help of surface plants. In subdued light, the fish look very beautiful, forming a neon tint. Daylight should not be more than 15 hours.
  4. Temperature conditions – automatic thermostats must be installed in the aquarium, with the help of which the water temperature will always be at the same level.

  • Soil– river sand and any pebbles are suitable. The fish look more advantageous against the background of a dark bottom, from which the rays of light are reflected.
  • Vegetation– fish love to hide in dense vegetation, so usually the right side of the aquarium is planted with plants, and a feeder is installed in the left. Surface plants are a must, creating partial shade.
  • Decor– the aquarium should have various snags, which, in addition to forming an attractive scape, additionally acidify the water.
  • Diet – since the rasbora has a relatively small and insufficiently mobile mouth, the food should be chosen plate-shaped, so that it does not sink quickly, but allows the fish to absorb it in small portions. The priority is "microfoods", which are ideal for "small mouths", contain everything necessary for the harmonious development of fish.
  • Peat extract, which has a high humic acid content and is present in higher concentration in the natural habitat, is essential for the upkeep of Rasbora Axelrodii.

    Although this material is not very expensive, it is necessary to discuss the long lifespan and procreation of fish in this species.

    Stress can be brought on by bright lighting and a dearth of vegetation. Stress can also cause appetite loss, reduced movement, and a desire to sink to the bottom. The quality and duration of life are drastically decreased in the absence of partial shade.

    Features of breeding

    The fish can reproduce in the aquarium without extra stimulation or removal if all the requirements are met. The female typically spawns in thickets of shaded plants, from which viable fry emerge after 72 hours of incubation and are able to find food on their own.

    It’s hard to characterize Rasbora as a loving parent. In addition, the parents and other flock members consider the eggs to be a delicacy. This is the reason why during spawning, breeders move the male and female to a different tank.

    Reproduction is artificially stimulated by increasing the amount of protein-rich foods in the diet and lowering lighting brightness.

    The fry are not viewed negatively by other fish and swiftly integrate into the school. But if you want them to gain weight quickly, you should feed them a lot of brine shrimp and microworms.
