How to groom goldfish

The term ‘grooming’ has often been met with ridicule when mentioned in relation to the care of goldfish. However, within the esteemed realm of the aquatics hobby, grooming represents the noble pursuit of nurturing these exquisite creatures to reach their utmost potential. The approach to this endeavor varies from individual to individual, and I shall now delve into my own meticulous procedures, which have yielded remarkable results.

Water Volume Requirements for Optimal Fish Growth

Adequate tank size is crucial for promoting the healthy growth of fish. In my professional assessment, goldfish, particularly the fancy varieties, necessitate a minimum of 20 gallons of water per individual. However, larger aquariums offer the possibility of accommodating more fish, such as having four individuals in a sixty-gallon tank instead of the typical three. I strongly discourage exceeding these limits unless using a 40-gallon breeder tank or larger.

Water Quality: Considering Tank Size and the Importance of Maintaining Optimal Conditions

In addition to addressing the appropriate tank size, it is crucial to emphasize the significance of water quality when caring for fish, including goldfish. The well-being of goldfish, as well as other fish species, relies heavily on the presence of good, clean water. It is noteworthy to mention that maintaining ideal conditions for fancy goldfish can prove to be more challenging compared to their single-tailed counterparts.

The rationale behind this distinction lies in the increased sensitivity of fancy goldfish to the presence of ammonia, nitrate, and nitrite in their aquatic environment. To ensure the best possible conditions for their health and longevity, I strongly recommend performing water changes ranging from 80% to 100% on a weekly basis. It is essential to note that this recommendation assumes that the necessary cycling process has already taken place to establish a stable and balanced ecosystem for the fish.


Among the various subjects I have addressed thus far, nutrition holds utmost significance, particularly when it comes to food. The selection of fish feed is a matter I feel particularly strongly about. I kindly urge you to refrain from employing any type of flakes, as they offer negligible nutritional value and, when introduced to water, merely create disorder. Moreover, flakes can lead to buoyancy issues and digestive problems in fancy goldfish. Instead, I highly recommend opting for gel food options such as Repashy Super Gold or Solient Green. Numerous homemade gel recipes can also be found online for your convenience.

A noteworthy aspect about goldfish is their affinity for dietary diversity, which is vital for their optimal growth. Introducing a high-quality pellet like Jappies Fish Food or New Life Spectrum into their diet can be beneficial. Additionally, treating them with a variety of fresh vegetables such as lettuce, spinach, or broccoli is advisable. It is important to feed them two to four times a day, providing only the amount that they can consume within two to three minutes.

Please bear in mind that uneaten food will contribute to water pollution and trigger ammonia spikes, which, if not promptly addressed, can have fatal consequences.


Filtration systems serve the purpose of eliminating uneaten food and waste products from the water, ensuring a pristine and hygienic environment within the tank. Additionally, filters foster the growth of beneficial bacteria that consume ammonia, subsequently converting it into nitrite and ultimately into nitrate, a significantly less harmful substance for fish.

These bacteria can be thought of as neutralizers. It is worth noting that these bacteria not only inhabit the filter itself but also reside in the substrate and various surfaces within the aquarium. They do not exist solely in the water, meaning that performing water changes will not eradicate them.

As a general guideline, it is recommended to have a filter that circulates the water volume within the tank eight to ten times per hour. For instance, a sixty-gallon tank should ideally have a turnover rate ranging from 480 to 600 gallons per hour. I strongly endorse the Aqua Clear 70 as an outstanding hang-on-back filter option.

Lastly, it is essential not to overlook the importance of rinsing your filter media during weekly water changes. learn more about goldfish
