15 Low-Maintenance Freshwater Fish for Beginners With Pictures
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.
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.
Easy to care for and with a unique appearance, the bristlenose plecostomus is a fun addition to any aquarium. You can use marine salt for saltwater tanks, freshwater salt for freshwater systems, kosher salt in emergencies, and Epsom salt for stress relief or specific diseases. Each type serves different purposes, so choose based on your aquarium’s needs.
Their peaceful nature and striking appearance make them a perennial favorite among beginner aquarists looking to create a vibrant underwater landscape. Don’t feed carnivores like Chinese Softshell Turtles plant-based food or overload omnivores like False Map Turtles with protein-rich food only. All 14 turtle species in this overview have unique care needs, but there are some general turtle tank maintenance rules that will help all of them.
