0  comments

Madagascar Rainbow fish is one of the most beautiful freshwater fish among all rainbow fish species. This freshwater fish is also sometimes known as Madagascan rainbow fish. So, here in this article, we will discuss all “Care for Madagascar Rainbow fish: Size, Lifespan, Tank Compatibility, and More.”

Let’s continue

Madagascar Rainbow fish are a few of the highly agile and active small species. So, these fish species also require some additional tank requirements. To accommodate the high activity level of Madagascar Rainbow fish, the aquarium should be designed with a large open area at the front. However, it is also essential to provide hiding places for the fish in the form of vegetation at the aquarium’s back and sides. They are excellent jumpers; always use a lid that fits snugly on the fish tank to prevent this from happening, and ensure that the water is well-oxygenated by using an oxygen pump and sponge filter.

Species Overview

Even though the Madagascar rainbow fish is generally considered to be one of the most peaceful kinds of rainbow fish, it is possible for them to be aggressive with smaller tankmates. They are an excellent addition to the tank because, if cared for properly, they will develop stunning patterns that are a reflection of their silvery scales, and they will do this. When maintained in groups, they offer a lot of excitement for the keeper to monitor, which is a positive point. Also, they are tolerant of a larger range of water parameters in comparison to species of fish that are more sensitive to changes in these characteristics. They should be kept in groups of at least eight individuals, and as a result, a moderate to enormous tank should be used to house them.

Origin And Distribution

This species of fish, known by its scientific name Bedotia madagascarensis or Bedotia geayi (old scientific name), is native to Madagascar. Typically, it may be discovered in the crystal-clear streams and canals that can be found to the north of Manambalo Creek and farther up the Ivoloina River on the island of Madagascar in Africa.

Appearance & Colors

The fish has a robust but relatively small dorsal fin and a long and thin body. Their mouths and eyes are both rather huge, and their coloring can range from grayish to silvery. The body has an overall tone that is somewhere between brown and light yellow, with a light blue shine to it. When they move their dorsal fins, they display a more complex range of colors, making them aesthetically pleasing. Sometimes, a bright blue stripe runs throughout the entirety of the fish’s body from head to tail.

How Do You Tell a Male from a Female Rainbow Fish in Madagascar?

Adult males display a noticeably higher degree of ornate coloring in the dorsal fins compared to adult females, and males generally have more vibrant coloration. On the other hand, females have larger bodies and less coloration.

Madagascar Rainbow fish Size

The length of an adult Madagascar Rainbow fish may reach up to 5.7 to 5.9 inches if proper nutrition is provided.

Madagascar Rainbow fish Lifespan

The life expectancy of a Madagascar Rainbow fish is nine to eleven years (only if proper care is provided). Water quality, nutrition, and handling significantly impact Madagascar fish lifespan.

Behavior & Temperament

The Madagascar Rainbow fish is not known to be aggressive against other fish and thrives in community aquariums with other fish of similar size and temperament.

It will be stressful for them if they are housed in a tank with aggressive fish that nibble at their fins. Do not house them with fish that are either too small or move too slowly since this will make it impossible for them to compete for food and result in malnourishment.

It is advised to retain only one specimen of this species in each tank since the adult males of this species can become violent against one another and possessive of their territory. Always ensure they are kept with peaceful tankmates who are the same size as them and have a similar temperament.

They are generally calm fish that will not annoy any of the tank’s other inhabitants, and they prefer hiding among vegetation with a dense cover of leaves. They won’t have any problems adjusting to living in a community aquarium with other docile species of a similar size.

    Clamped fins and tiny black spots on the skin are the common signs of this condition. You’ll most likely need a magnifying glass to view these spots. If you keep your tank tidy and remove any potential sources of stress, you can quickly treat and avoid this, too.

    Hole in the head disease

    Affected Rainbow fish with this disease may often show signs of depression in the area around the head, in addition to losing their appetite and becoming listless. Antibiotics are the standard course of therapy for Hole in the Head Disease; however other procedures may be necessary.

    The Madagascar Rainbow fish is susceptible to a parasite called Hexamita.  This parasite causes weakness and a loss of appetite.

    If you find this parasite in your tank, chances are the tank conditions are subpar. The greatest defense against this parasite is a healthy tank environment.

    Bacterial infections

    Although bacterial infections in this type of fish are uncommon, they can occur if the aquarium environment is not maintained correctly. Having hazy eyes, pinched fins, or a lack of activity are all signs of a bacterial illness.
