Choosing The Right Tank
Choosing the right tank is important for keeping discus fish healthy. The tank size, shape, and material all affect the fish’s comfort and growth.
It is best to pick a tank that suits your space and meets the needs of discus fish. This guide will help you decide on the best tank setup.
Ideal Tank Size
Discus fish need enough space to swim and grow. A tank that is too small can cause stress and health problems.
A good minimum size for a discus tank is 50 gallons. This size allows room for at least five discus fish.
- 50 gallons for 5 discus fish
- Add 10 gallons for each extra fish
- Keep the water clean with a good filter
Tank Shape Considerations
The shape of the tank can change how your discus fish swim and how you maintain the tank.
Long tanks offer more horizontal swimming space. Tall tanks provide more water volume but less swimming space.
| Tank Shape | Advantages | Disadvantages |
|---|---|---|
| Long | More swimming space, easier to arrange plants | Takes up more floor space |
| Tall | More water volume in less floor space | Less horizontal swimming room |
| Square | Good balance of space and volume | May limit swimming paths |
Material Options
Tanks come in glass and acrylic. Each material has benefits and drawbacks.
Glass Tanksare heavier and less expensive. They resist scratches but can break if dropped.
Acrylic Tanksare lighter and clearer. They resist impact but scratch easily.

Essential Equipment
Setting up a discus tank needs the right equipment for a healthy environment. This guide covers the basics every beginner should know.
Good equipment helps keep water clean, temperature stable, and lighting suitable for your fish.
Filtration Systems
Filtration is key to remove waste and keep water clear. Choose filters that handle the tank size well.
- Canister filters: Powerful and quiet, good for large tanks.
- Hang-on-back filters: Easy to install and maintain.
- Sponge filters: Gentle for small tanks and fry.
Heating Requirements
Discus fish need warm water to stay healthy. Use a reliable heater with a thermostat.
| Water Temperature | Recommended Range |
| Discus Fish | 82°F to 86°F (28°C to 30°C) |
| Heater Type | Submersible with thermostat |
| Backup | Thermometer to monitor temperature |
Lighting Choices
Proper lighting supports fish health and shows their colors. Avoid bright lights that stress them.
- Use soft LED lights designed for aquariums.
- Keep lights on 8 to 10 hours daily.
- Include plants or decorations to give shaded areas.
Water Parameters
Setting up a discus tank needs careful attention to water. Water parameters affect the health and growth of discus fish. Good water conditions help discus feel safe and active.
Beginners should learn the key water settings for discus tanks. These include temperature, pH, hardness, and cleanliness. Keeping these stable is important.
Optimal Temperature
Discus fish prefer warm water. The best temperature is between 82 and 86 degrees Fahrenheit. This range helps their metabolism and immune system.
Use a reliable heater to keep the water steady. Avoid sudden temperature changes because they stress the fish. Check the temperature daily.
Ph And Hardness Levels
Discus fish like soft, slightly acidic water. The pH should be between 6.0 and 7.0. Water hardness should be low to moderate.
- pH level: 6.0 to 7.0
- General Hardness (GH): 1 to 8 dGH
- Carbonate Hardness (KH): 1 to 3 dKH
Test your water regularly with a test kit. Adjust the pH or hardness slowly if needed. Sudden changes can harm discus.
Maintaining Water Quality
Clean water is essential for discus health. Remove waste and uneaten food to keep water clear. Use a good filter for steady water flow.
Do partial water changes weekly. Replace 25% to 30% of the tank water with fresh, treated water. This keeps toxins low and oxygen high.
- Use a quality water filter
- Change 25-30% water weekly
- Test ammonia, nitrite, and nitrate levels
- Keep ammonia and nitrite at 0 ppm
- Keep nitrate under 20 ppm
Substrate And Decorations
Setting up a discus tank requires careful choice of substrate and decorations. These elements help create a healthy and natural environment for your fish.
Good substrate and decorations also improve the tank’s look and give your discus places to explore and hide.
Best Substrate Types
Discus fish like soft and fine substrate that is gentle on their bodies. Avoid sharp or rough materials.
- Fine sand: Soft and safe for discus to dig in.
- Clay-based substrates: Help keep water pH stable and slightly acidic.
- Gravel (small and smooth): Can be used but not as ideal as sand.
Aquascaping Tips
Arrange decorations to mimic the natural habitat of discus fish. Keep open swimming areas and shaded spots for resting.
- Place taller plants or driftwood in the back or corners.
- Use smooth stones or rocks to create hiding spots.
- Leave space in the center for swimming.
- Keep decorations stable to avoid falling and harming fish.
Safe Plants And Ornaments
Choose plants and ornaments that do not harm discus or change water quality quickly. Avoid sharp edges and toxic materials.
| Plant/Ornament | Benefit | Notes |
| Anubias | Hardy, grows well in low light | Attach to driftwood or rocks |
| Amazon Sword | Large leaves provide shade | Requires nutrient-rich substrate |
| Driftwood | Natural hiding spots, lowers pH | Soak before use to avoid water cloudiness |
| Smooth River Stones | Safe decoration, no sharp edges | Easy to clean |
Selecting Discus Fish
Choosing the right discus fish is key to a successful tank setup. You need to pick healthy fish that fit your tank size and goals.
This guide will help you select discus fish that are healthy, compatible, and suitable for your aquarium.
Healthy Fish Traits
Healthy discus fish show clear eyes and smooth scales. Their fins stay intact without tears or spots.
They swim actively and respond to food quickly. Avoid fish that hide or look weak.
- Clear, bright eyes
- Smooth, shiny scales
- Intact fins without damage
- Active swimming behavior
- Good appetite and response to food
- No visible signs of disease or parasites
Choosing Compatible Species
Discus fish are peaceful and need calm tank mates. Avoid aggressive fish that may stress them out.
Good companions include small tetras, corydoras, and dwarf cichlids. These species share similar water needs.
- Small, peaceful tetras
- Corydoras catfish
- Dwarf cichlids like Apistogramma
- Avoid large or aggressive fish
- Choose species with similar water temperature and pH needs
Stocking Density Guidelines
Discus fish need plenty of space to swim. Overcrowding causes stress and health problems.
Plan to keep 1 discus per 10 gallons of water. This keeps water quality high and fish happy.
- 1 discus fish per 10 gallons (38 liters) of water
- Adjust numbers for tank size and filtration
- Leave space for plants and decorations
- Monitor fish behavior for signs of stress
- Reduce stocking if water quality drops
