13 Easiest Fish to Take Care of in a Low Maintenance Aquarium

How To Maintain A Freshwater Aquarium: Essential Tips For A Clean And Healthy Tank

The larger the tank, the smaller the chance of mistakes having a huge impact. Use the bucket with the siphoned water to give the filter a good rinse. You’ll need the bucket for the water you’ll be siphoning out during water changes. In low levels, nitrates are not harmful for your fish, but high levels are toxic. Once ammonia and nitrite levels are no longer detectable and you can detect nitrates, it means the cycle is completed. This ammonia is highly toxic for you fish, so what you need to do is perform a fishless cycle.

Choosing Fish and Aquatic Plants

Betta fish would also need hideaways, which are easily achievable with the help of a couple of live aquatic plants. This is thanks to their unique labyrinth lungs, which allows them to breathe atmospheric air. For this reason, some people do not see the need for a filter in an aquarium with a Betta fish.

How to Maintain a Freshwater Aquarium: A Complete Guide to Keeping Your Tank Clean and Healthy

  • Native to Southeast Asia, the pearl gourami is not only strikingly attractive but also very easy to take care of.
  • It’s better to feed smaller amounts more frequently than a large amount at once.
  • While frequent water changes are generally beneficial, changing fish tank water daily is usually not necessary and can even be detrimental.
  • Don’t panic; with care and observation, your fish will stay healthy and happy.
  • Wastes can pollute the water when degrading threatening the life of aquarium fish.

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.

Even if you’ve chosen hardy fish as your starter fish, you’re still going to expose them to toxins, which will eventually reflect in their health. It goes without saying that adding small fish to a tank with larger fish is also a no-no, since the bigger fish will mistake the smaller ones for food. So, you’ll need to perform water changes and clean the tank regularly to keep nitrate levels under control. If you add fish to a tank that hasn’t gone to a cycling process, ammonia levels will spike because of the waste fish generate.

Stable water conditions and a balanced diet of flake food, supplemented with occasional live or frozen treats, will support their health and vibrant colors. Beginners will appreciate their easygoing nature and the lively dynamics they introduce to the tank. While they can adapt to a variety of water conditions, maintaining clean and well-oxygenated water will ensure their health and happiness. Their diet should include sinking pellets and occasional live or frozen foods to mimic their natural foraging habits.

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.
