Choosing The Right Tank Setup
Setting up a neon tetra tank needs careful planning. The right setup helps fish stay healthy and look bright.
This guide covers tank size, substrate, and lighting choices. Each affects the tank’s look and fish well-being.
Ideal Tank Size For Neon Tetras
Neon tetras are small but active fish. A bigger tank gives them space to swim happily.
At least 10 gallons is good for a small group. More fish need a bigger tank to avoid crowding.
- 10 gallons for 6-8 neon tetras
- 20 gallons for 15 or more neon tetras
- Long tanks offer more swimming space
Selecting Suitable Substrate
Substrate is the material at the tank bottom. It affects plant growth and fish comfort.
Fine gravel or sand works well for neon tetras. They like soft textures that don’t hurt their fins.
- Use dark substrate to show fish colors
- Choose inert substrates to avoid water changes
- Add nutrient-rich soil if growing live plants
Lighting Options For Vibrant Colors
Lighting affects how neon tetras and plants look. Bright light brings out fish colors well.
Use LED lights with a daylight spectrum. Avoid strong light that stresses fish or causes algae.
- LED lights with 6500K color temperature

Hardscape Elements And Layout
Aquascaping shapes the look and feel of your neon tetra tank. Hardscape elements like rocks and driftwood create structure and interest. A good layout helps fish feel safe and swim freely.
Plan your tank’s hardscape with balance and natural style. Thoughtful placement of objects will enhance the tank’s beauty and comfort for neon tetras.
Using Driftwood And Rocks
Driftwood and rocks add texture and height to the tank. They mimic the natural environment of neon tetras. Choose pieces that are smooth and safe for aquarium use.
Arrange driftwood and rocks to create layers and depth. Avoid overcrowding so fish can swim easily. Combine different sizes and shapes for a natural look.
- Use driftwood to create vertical interest
- Place rocks to form caves or ledges
- Balance heavy pieces with open spaces

Creating Natural Hiding Spots
Neon tetras need places to hide and feel safe. Use driftwood and rocks to build small caves and nooks. Plants can also add shelter and soften hardscape edges.
Hiding spots reduce stress and encourage natural behavior. Position these spots in quiet corners or near the tank bottom. Make sure they are easy to access but not too dark.
- Combine rocks to form caves
- Use driftwood to make overhangs
- Add dense plants near hiding areas
- Leave entrances wide enough for fish
Balancing Open Swimming Areas
Neon tetras love to swim in open spaces. Keep some areas free of decorations and plants. This lets the fish swim in groups and show off their colors.
Balance open spaces with hardscape to create a natural flow. Avoid blocking the entire tank with decorations. Open zones improve water movement and tank health.
- Leave mid and upper water clear
- Place hardscape mostly near bottom or sides
- Create open channels for swimming paths
- Keep space around feeding areas free
