FAQ
What kind of fish are best suited for a 28 litre tank?+
Smaller, peaceful tropical species thrive in this size. Neon tetras, guppies, or small platies are excellent choices due to their compatibility and relatively low space requirements. Avoid larger or more aggressive fish that would quickly outgrow the tank.
What filter do I need for a 28 litre aquarium?+
A sponge filter is generally recommended as it provides gentle filtration without disrupting the delicate ecosystem within the tank. Mechanical filtration (removing debris) and biological filtration (housing beneficial bacteria) are both crucial for maintaining water quality.
What temperature should I set my heater to?+
Most tropical fish prefer a water temperature between 24°C and 28°C. Invest in a reliable aquarium heater with adjustable settings to maintain a stable temperature suitable for your chosen species.
How often should I clean the gravel?+
Partial water changes (around 25%) every two weeks are usually sufficient. Avoid completely cleaning the gravel as this removes beneficial bacteria essential for the nitrogen cycle.
What substrate is best for a 28 litre tank?+
Fine gravel or sand are suitable substrates, providing an area for beneficial bacteria to colonize and contributing to the overall aesthetic of the aquarium.
Do I need extra lighting?+
While not always essential, LED lighting can enhance the appearance of your fish and plants. Choose a low-intensity light source that mimics natural daylight conditions.
How much water should I add during a water change?+
Change approximately 25% of the water during each partial water change to maintain proper water quality and remove accumulated nitrates.
What are the benefits of using bottled water for my aquarium?+
Using dechlorinated, bottled water eliminates chlorine and heavy metals which can be harmful to fish. Ensure the water is temperature-matched before adding it to your tank.
How do I cycle a new 28 litre aquarium?+
The nitrogen cycle needs to establish itself – this takes several weeks. Adding a bacterial starter product speeds up the process, but still requires careful monitoring of ammonia and nitrite levels.
Can I add live plants to a 28 litre tank?+
Yes, small, slow-growing plants like Java moss or Anubias are well-suited for this size aquarium. They contribute to water quality and provide hiding places for your fish.
