15 Low-Maintenance Freshwater Fish for Beginners With Pictures

Freshwater Aquarium Fish for Beginners Easy Fish to Keep Alive

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.

How to keep a freshwater aquarium clean naturally?

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.

  • Their unique swimming action is generated by a plastic lip and curved body, which make the lures dive and wiggle just by reeling them in.
  • Different types of tanks require specific amounts of salt for optimal conditions.
  • They are also frequently sold in bright, interesting colors under the “Glofish” branding, and Zebra Danios also come in a long-finned variety.
  • Use the bucket with the siphoned water to give the filter a good rinse.
  • Whether you’re a beginner aquarist or a seasoned fishkeeper looking for some tips, read on to find out how to maintain a healthy and vibrant underwater world.

An aquarium that’s safe for fish will read 0 ppm (parts per million) of ammonia, 0 ppm nitrite, and around 10 ppm of nitrate. Therefore, it’s not recommended to keep fish in an aquarium without a running filter for more than a week and that’s pushing it. Generally, the fish for an aquarium of this size should not be an over-breeder or a fast-grower. A 5-gallon bowl with some live plants would make a good habitat for a single male Betta. Such small volumes of water get polluted by organic waste very quickly and sudden ammonia spikes, deadly for aquatic inhabitants, are often observed. Betta fish, which has a unique organ called the Labyrinth, is one kind of fish that can survive such low-oxygen environments.

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.

To add to their appeal as low-maintenance fish, they are omnivorous and can subsist on a diet of most store-bought fish flakes. Parents need not worry about obtaining specialized food or having to isolate the neon tetras in a separate tank. Their hardiness also makes them resilient against any mistakes that might be made as part of the learning curve. Did you know that 2 million Neon Tetras are sold in the US every month?

How do I monitor salt levels in my aquarium?

By understanding the specific needs of your tank and the types of salt available you can create a thriving environment for your fish. Implement these practices to maintain optimal salt levels and support the well-being of your aquatic pets. Plecos are generally placid and easy to care for, so they are not challenging for beginners.
