A Complete Guide to Freshwater Fish Tanks: Selection, Setup, and Maintenance
Imagine sharing your aquarium tales and getting advice about that stubborn algae problem. You’ll find forums and social media groups where members post about their experiences. Discussions cover everything from tank setups to favorite fish foods.
The substrate or gravel will be a big factor in which types of decorations work in your tank. When you choose which fish you want, this can depend on which gravel you chose. A sandy bottom will give your tank more of a saltwater look, but it is more difficult to work with. Glass stones are pretty but don’t offer much for healthy bacteria to grow on. Once you decide on all the different parts it is time to move on to cycling your tank to get it ready for your fish. Say goodbye to the complexities of water parameters and say hello to a tailored aquatic experience with fish that thrive in a wide range of conditions.

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.
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.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.
