Select an aquarium size that suits your available space and budget. Larger tanks provide more stability and options for fish species but require more maintenance.
Place your aquarium in a stable location away from direct sunlight and temperature extremes. Ensure your chosen surface can support the tank's weight.
Invest in a reliable filtration system to maintain water quality and oxygenate the tank. Ensure the filter's flow rate matches your tank size.
Lay a suitable substrate, like gravel or sand, and add decorations that complement your chosen fish species.
Before adding fish, cycle the tank to establish beneficial bacteria. This process can take several weeks and ensures a stable and healthy environment for your fish.
