- Affordable Care: Low-maintenance fish generally require less food and fewer water changes than more demanding types, resulting in lower overall costs for maintenance.
- Lower Risk of Disease: Low-maintenance fish typically have fewer issues with disease than other types, as they are not as prone to stress from poor water conditions and other sources.

Factors to Consider When Choosing Low-Maintenance Fish
When selecting low-maintenance fish for your tank, there are a few factors you should consider before making your purchase. Here are the top factors to keep in mind:

- Water Parameters: Not all species of low-maintenance fish can tolerate large fluctuations in water parameters such as pH levels or salinity. Research which types of fish can live comfortably in the given environment of your aquarium.
- Compatibility: Low-maintenance fish tend to be more peaceful and therefore many species can live safely together without causing any issues or stress to one another. However, some types may become territorial or aggressive with certain other species, so it’s important to do research beforehand on compatibility for any potential additions to the tank.
- Diet Requirements: All fish require proper nutrition, however, some types of low-maintenance fish may have specialized dietary needs that will require specialized care and feeding habits.
