15 Low-Maintenance Freshwater Fish for Beginners With Pictures
You can’t go wrong with performing weekly 10-15% water changes that will physically remove excess waste and dilute toxins. Just because your fish will keep on eating after you’ve fed them the recommended amount of food, it doesn’t mean they’re always hungry. Of course, all these can be avoided with proper care and maintenance. After you complete the nitrogen cycle, you’ll still need to monitor toxin levels to see if there are any changes you should be aware of. The resulting number will tell you the total length of mature fish you can keep in the tank.
Be prepared to take at least a few weeks to ensure your tank is fully cycled before bringing your fish home. If you don’t have the time to skim through that article, my quick recommendation would always be to use Tetra SafeStart Plus. This brand contains the actual species of ammonia-consuming bacteria that thrive in water, unlike some other brands that use a less-efficient terrestrial strain.
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.
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.
Being a cold-water fish, the White Cloud Mountain Minnows can comfortably carry on in an aquarium even if it has no water heater. Having floating plants in the tank will give even more confidence to the fish, which in turn makes their behavior super entertaining. The Lambchop Rasbora fish do not require very soft water, but they do come from a habitat that’s a little on the softer end. These aquarium kits are beginner-friendly and come with almost all the needed equipment to start (except a heater).
