FAQs
To start a fish aquarium, choose an appropriate tank size, install a filter, heater, and lighting, then add substrate and fill with dechlorinated water. Cycle the tank for 2-4 weeks to establish beneficial bacteria before adding fish, and always test water parameters like pH, ammonia, and nitrite before introducing any livestock.
A cloudy fish aquarium is most commonly caused by a bacterial bloom during the nitrogen cycle, indicating the tank is still establishing its biological filter. Other causes include overfeeding, excess waste, dirty substrate, or an imbalanced pH - performing a partial water change and reducing feeding usually resolves the issue within a few days.
To build a fish aquarium, cut glass panels to size, bond them together using aquarium-safe silicone sealant, and allow 24-48 hours to cure before testing for leaks. Once sealed, add a substrate, filtration system, heater, and lighting, then cycle the tank before adding fish to ensure a safe and stable environment.
The best freshwater fish for a tank include Betta fish, Neon Tetras, Guppies, Corydoras Catfish, and Mollies, as they are hardy, beginner-friendly, and adaptable to a range of water conditions. For community tanks, peaceful species like Danios and Platies are also excellent choices due to their compatibility and low maintenance needs.
Australia is home to a diverse range of native freshwater fish including Murray Cod, Golden Perch, Silver Perch, Australian Bass, and the iconic Barramundi. Many exotic species such as Goldfish, Carp, and Tilapia have also been introduced and are now widespread across Australian waterways, often posing a threat to native fish populations.
The general recommendation for aquarium salt in freshwater tanks is 1 tablespoon per 5 gallons (19 litres) of water for general health maintenance and disease prevention. Not all freshwater fish tolerate salt - scaleless fish like Corydoras and live plants are sensitive to it, so always research your specific species before adding salt to the tank.
