10 Low Maintenance Fish: The Easiest Fish to Care for in Your Aquarium
Use the gravel vacuum to remove leftover food and debris from the gravel. Along with water changes, this will reduce nitrate levels in the tank and keep your fish healthy. Maintaining a freshwater aquarium can sometimes feel like a balancing act. This section highlights common challenges like water cloudiness and fish health. Heaters maintain the ideal temperature to suit specific fish species.
Sand gives a more natural look and is best for species that like to dig. If you plan to grow plants, consider a nutrient-rich substrate that supports plant roots. You should change about 15 to 25% of your aquarium’s water every one to two weeks. When you change your aquarium’s water, you should clean the rest of the tank as well. The percentage of water and frequency of water changes depend on the volume of fish and plant life in your tank. A heavily stocked tank will need a larger volume of water changed more frequently, and a lightly stocked tank can be changed slightly less.

While they prefer to be kept with six to eight of their own kind, they don't need to be housed in a species-specific tank thanks to their gentle nature. A hardy species of fish native to China, the white cloud mountain minnow is a graceful and peaceful community fish that likes to be paired with at least five others of its species. Measuring 1.5 inches in length and living for around three to five years, they're a good fish for beginners and are easy to breed. White cloud mountain minnows do not like heat and need to be kept in water with a temperature below 72°F.

This might signal high ammonia or nitrite levels, which means it’s time for a water change and proper filtration. Regular water changes are necessary for a balanced aquarium environment. Also, limit the light duration to reduce algae growth, creating a balanced environment for your aquatic life. Regular use of a gravel vacuum helps pick up uneaten food and fish waste, which can lead to harmful ammonia levels. Adjustable heaters are a good investment since you can tweak the temperature if needed.
These shoaling fish are easy to care for and can thrive in cooler water temperatures, which makes a heater not always necessary for their care. Betta fish are one of the most popular freshwater fish due to their low-maintenance nature and flowing, colorful fins. They have a labyrinth organ, which allows them to breathe surface air in low-oxygen environments. They have simple feeding requirements and will be happy in a tank with plants, a heater, and plenty of space to swim.
Beginner will often select fish based on their personal preferences without much regard to water conditions and compatibility. Multiply this by 75%, and you’ll get 12, which means you can keep a total of 12 inches of mature fish in your tank. Use the fish net to remove any dead plants or fish and use the algae scrub to clean the glass surfaces and other tank decorations. Tank maintenance should be carried out regularly to keep the tank clean and toxin levels low. Even though some fish are known to get along, it’s still a good idea to monitor tank behavior when building a community tank. Platies, Mollies and Guppies are great beginner-friendly fish that get along with each other in a community tank.
