FAQ

What kind of fish can I keep in a 14 litre tank?+

Due to the limited space, it’s best to choose small, peaceful species. Neon Tetras, Guppies, White Cloud Mountain Minnows, and Endler's Livebearers are all good options that won’t quickly outgrow the tank.

What filter do I need for a 14 litre aquarium?+

A sponge filter is ideal for a 14 litre tank as it provides gentle filtration without disrupting the delicate ecosystem. Avoid using strong currents which can stress the fish. Ensure you regularly clean the filter to maintain its effectiveness.

What substrate should I use in my 14 litre aquarium?+

Fine gravel or sand is suitable for a 14 litre tank. A layer of approximately 2-3cm will provide a surface area for beneficial bacteria to colonise, which is crucial for the nitrogen cycle.

How often should I do water changes in a 14 litre tank?+

Regular water changes are essential – aim for 20-25% of the water volume every week or two. This removes waste products and replenishes minerals, maintaining water quality.

What temperature should I keep my fish at in a 14 litre aquarium?+

Most tropical freshwater fish thrive in temperatures between 22°C and 26°C (72°F and 79°F). A reliable thermometer is crucial for monitoring the water temperature accurately.

Do I need a heater for my 14 litre tank?+

While not always strictly necessary, a small submersible heater can help maintain a stable temperature, especially in cooler rooms. Ensure the heater has an adjustable thermostat to prevent overheating.

What plants are suitable for a 14 litre aquarium?+

Small, slow-growing plants like Java Moss, Hornwort, and Anubias are excellent choices for a 14 litre tank. They provide cover for fish and help maintain water quality by absorbing nitrates.

How do I cycle my new 14 litre aquarium?+

Cycling involves establishing beneficial bacteria that convert harmful ammonia into less toxic substances. You can use a commercially available starter to speed up the process or add a small amount of fish food to provide an initial source of nitrogen.

What lighting do I need for my 14 litre aquarium?+

Low-light conditions are ideal for most freshwater fish and plants in a 14 litre tank. LED lights designed for aquariums can provide sufficient illumination without overheating the water.

Can I keep shrimp in a 14 litre aquarium?+

Yes, small species of shrimp such as Cherry Shrimp or Neocaridina Shrimp can be kept in a 14 litre tank, provided you maintain good water quality and offer plenty of hiding places. Avoid overcrowding the tank.
