• Provide 8 to 12 hours of light daily
• Use a timer to keep light consistent

Adjust lighting based on your fish and plants. Some fish prefer dim light, while plants need bright light.

Aquascaping Basics

Aquascaping means arranging plants, rocks, and decorations in a fish tank. It creates a natural and beautiful home for tropical fish.

Good aquascaping helps fish feel safe and shows off their colors well. It also keeps the water healthy and clear.

Substrate Selection

The substrate is the material that covers the bottom of your tank. It can be sand, gravel, or soil made for plants.

Choose a substrate that fits your plants and fish. Some plants need nutrient-rich soil to grow well. Sand is good for fish that like to dig.

• Use fine sand for bottom-dwelling fish
• Choose nutrient-rich soil for live plants
• Gravel works well for easy cleaning

Plant Choices And Placement

Pick plants that match your tank size and light conditions. Some plants need more light, while others grow in low light.

Place tall plants at the back and sides. Put shorter plants in the front. This layout looks natural and keeps space for swimming.

• Java fern and Anubias grow well on rocks
• Amazon swords do best in nutrient soil
• Use moss for ground cover or decoration
• Keep open space for fish to swim freely

Decor And Hiding Spots

Decorations add beauty and make hiding spots for shy fish. Use natural items like driftwood and rocks.

Hiding places reduce stress and help fish feel safe. Make sure the decor does not have sharp edges that could hurt fish.

• Driftwood adds a natural look and shelters fish
• Rocks create caves and ledges for hiding
• Leaf litter can provide cover and food
• Avoid plastic decor with rough surfaces
