Step-by-Step Guide:
- Let’s begin by selecting the right tank size. Although it might seem counterintuitive, larger tanks are actually easier to maintain. They offer better water quality and a more stable environment, which is crucial for the well-being of your fish.
- The next crucial step is preparing the water. Start by filling your tank with tap water and using a water conditioner to remove harmful chemicals such as chlorine and chloramine. These contaminants can be lethal to fish. Additionally, it’s important to ensure nitrifying bacteria is present, as they play a vital role in the nitrogen cycle by breaking down harmful ammonia into less toxic compounds. You can purchase live nitrifying bacteria to jump-start this process. Adding fish immediately, without nitrifying bacteria present, can stress them due to an unestablished environment.
- With the water prepared, it’s time to set up the filtration system. A hang-on-back filter is a great choice for beginners due to its ease of use and efficiency in maintaining clean water. A hang-on-back filter also provides agitation to the water surface to allow for oxygen transfer. Wish breathe oxygen like us, so oxygenated water is critical.
- Next, a heater is essential. While tropical fish require heat to keep a warm temperature of 76-82 degrees Fahrenheit, all indoor fish require a heater to prevent shock – even goldfish!
- (Optional) To enhance the aesthetics and functionality of your tank, consider adding substrate like gravel or sand. Decorations can also be added to provide hiding spots and reduce stress for the fish. An air stone can improve oxygenation for bigger tanks when the hang on back filter is not enough (over 30 gallons). A light is important for both the fish and any plants you might add. Be cautious with natural light, as it can increase algae growth. If your tank is set against a wall, an aquarium background to match your chosen design elements can be obtained from your local pet store and taped to the back of your aquarium, Not only will a background enhance the look of your tank, but it may also provide some comfort for shy fish so they do not feel exposed on all sides.
- Finally, selecting your favorite tropical fish. So-called “community” fish are friendly with other community fish and can be added without worry. Examples include tetras and rasboras. Do not over-stock the tank which will result in an unhealthy living environment for your fish. Remember the rule of thumb: do not add more inches of fish than the gallons of water in your tank. That is, no more than 20 one-inch fish in your 20 gallon aquarium.
