Fish Size

Boesemani rainbowfish are a small to medium sized species. Adult fish can grow to between 4-6 inches in length.

When kept in an aquarium, boesemani rainbowfish will do best in a tank that is at least 30 gallons in size. A larger tank is always better though, as these fish love to swim and explore their surroundings.

Tank Size & Conditions

They are relatively easy to care for, but there are a few things to keep in mind when it comes to their tank size and conditions.

Boesemani rainbow fish should be kept in an aquarium that is at least 30 gallons in size. They prefer a well-planted tank with plenty of hiding places. A sandy substrate is best, as they like to dig and sift through the sand.

Water conditions are important for boesemani rainbow fish. They prefer a neutral pH (6.8-7.2), and a water temperature of 72-78 degrees Fahrenheit. They are not very tolerant of changes in water parameters, so it is important to keep a close eye on your aquarium conditions and make any necessary adjustments slowly and carefully.

Boesemani rainbow fish are social creatures and do best in groups. A group of 6 or more fish is ideal. They are not overly aggressive, but can be territorial with other fish of the same species, so it is best to keep them with other peaceful community fish.

With proper care, boesemani rainbow fish can be a beautiful and low-maintenance addition to your aquarium.

Water Parameters

Boesemani Rainbow fish are tropical freshwater fish that require a well-balanced aquarium with the correct water parameters. The ideal water parameters for Boesemani Rainbow fish are: 

pH level: 6.5-7.5

Water temperature: 72-78 degrees Fahrenheit

Ammonia levels: 0 ppm

Nitrite levels: 0 ppm

Nitrate levels: 0-20 ppm

Boesemani Rainbow fish are very sensitive to changes in water parameters and even small fluctuations can cause stress or disease. It is important to test the water regularly and make sure the parameters are within the ideal range.

Water Flow Rate

The water flow rate is an important parameter to consider when setting up a Boesemani rainbow fish tank. The Boesemani rainbow is a native fish of fast-flowing rivers and streams in Indonesia and needs a high water flow rate to stay healthy in captivity. A minimum water flow rate of 10 gallons per minute (GPM) is recommended for a Boesemani rainbow fish tank.

Too little water flow can cause the Boesemani rainbow to become stressed and susceptible to disease. A water flow rate that is too high can also be detrimental to the fish and cause them to become agitated and stressed. The optimal water flow rate for a Boesemani rainbow fish tank is 20-30 GPM.

When choosing a filter for your Boesemani rainbow fish tank, be sure to select one that is capable of providing the desired water flow rate. Canister filters and power filters are both suitable choices for a Boesemani rainbow fish tank. Be sure to clean and maintain your filter according to the manufacturer’s instructions to ensure optimal water quality and flow rate.

 pH Level

The pH level of a Boesemani Rainbow’s water is important to maintain for the health of the fish. The pH level should be between 6.5 and 7.5. If the pH level is too low, the fish may experience stress and be more susceptible to diseases. If the pH level is too high, the fish may experience respiratory problems.

Water Hardness

Water hardness is a measure of the amount of dissolved minerals in water. The more minerals present, the harder the water is.

Hard water is not necessarily a bad thing. In fact, many aquarists believe that a certain amount of hardness is essential for the health of their fish.

That said, too much hardness can be a problem. When the water is too hard, it can be difficult for fish to absorb the oxygen they need from the water. This can lead to stress and even death.

The ideal hardness for a boesemani rainbow tank is between 4 and 8 dGH.

Tank mates

Boesemani rainbows are peaceful fish that make great tank mates for other community fish. They are not known to be fin nippers, and will do well with other peaceful fish of similar size. Some good tank mates for boesemani rainbows include:

  • Guppies
  • Platies
  • Mollies
  • Swordtails
  • Danios
  • Barbs

Boesemani rainbows are also compatible with most peaceful invertebrates, such as shrimp and snails.

Diet & Feeding

Boesemani rainbowfish are not particularly fussy eaters and will accept most common aquarium foods. However, like all fish, they will thrive best on a diet that is varied and nutritious.

In the wild, these fish are omnivores, feeding on both plant and animal matter. In the aquarium, a good quality flake or pellet food should form the base of the diet, supplemented with live, frozen or freeze-dried foods for added variety.

Unique Boesemani Rainbow

Bloodworms, brine shrimp and daphnia are all good options and will help to bring out the bright colours of the fish. As well as being a nutritious treat, live foods can also help to stimulate the appetite of fish that are a little reluctant to feed.

It is also a good idea to offer some blanched vegetables such as spinach or cucumber from time to time. This will help to ensure that the fish are getting the full range of nutrients they need.

Generally speaking, Boesemani rainbowfish are not greedy eaters and should not be overfed. A couple of small meals per day should be sufficient.

Breeding

Boesemani rainbows are easy to breed in an aquarium setup. They are egg-layers, and the female will lay several hundred eggs at a time. The eggs will hatch in about two days, and the fry will be free-swimming a few days after that.

To induce spawning, the water temperature should be raised to around 80 degrees Fahrenheit. The male will then build a nest out of plants and debris, into which the female will lay her eggs. Once the eggs are laid, the parents should be removed from the tank, as they will likely eat their own young.

The fry can be fed small live foods such as brine shrimp or microworms. They will grow quickly, and can be moved to a larger tank after a few months.
