Setting up a successful aquarium requires careful planning. You’ll need a tank of appropriate size (depending on the fish), a filter, a heater (for tropical fish),
a substrate (gravel or sand), and decorations. Research your chosen fish species beforehand to determine their specific needs. For example, a betta fish requires a smaller tank than a goldfish. Cycle your tank properly before introducing any fish to establish beneficial bacteria that break down waste.
Maintaining Water Quality
Water quality is crucial for the health of your fish. Regular water changes (typically 25% weekly) are essential to remove waste and maintain optimal parameters. Test your water regularly using a reliable test kit to monitor ammonia, nitrite, nitrate, and pH levels. Maintain appropriate temperature levels based on your fish species. Neglecting water quality can lead to illness and death.
