Choosing The Right Tank
Choosing the right tank is key to a happy angelfish. The tank size, shape, and placement affect their health and comfort. This guide helps beginners pick the best tank.
Angelfish need enough space to swim and grow. A suitable tank also makes maintenance easier. Consider these points before setting up your tank.
Tank Size Recommendations
Angelfish grow tall and need vertical space. A tank that is too small can stress them and limit growth. A good tank size keeps them healthy.
- A minimum of 20 gallons is best for one angelfish.
- For a pair, choose a 30-gallon tank or bigger.
- More fish means a larger tank to avoid overcrowding.
- Tall tanks give angelfish room to swim up and down.
Selecting Tank Shape
Tank shape affects angelfish movement and water flow. Tall tanks suit angelfish better than long, shallow tanks. The shape can also impact decoration and filter choice.
| Tank Shape | Pros | Cons |
|---|---|---|
| Tall | More vertical space, fits angelfish swimming style | Less surface area for oxygen exchange |
| Long | Good for community tanks, more surface area | Less vertical space for angelfish |
| Square | Balanced space, easier to decorate | May be bulky and heavy |
Placement Tips
Where you place your tank affects angelfish health. Avoid spots with direct sunlight or strong drafts. Stability helps keep water conditions steady.
- Place the tank on a strong, level surface.
- Keep the tank away from windows to avoid temperature changes.
- Choose a quiet spot to reduce fish stress.
- Allow space around the tank for maintenance access.

Essential Equipment
Setting up an angelfish tank needs the right tools. These tools keep your fish healthy and happy.
Below are the key equipment types you need to start your aquarium properly.
Filters And Aeration
Filters clean the water by removing waste and toxins. Aeration adds oxygen to the tank, helping fish breathe well.
- Use a sponge or canister filter for gentle water flow.
- Install an air pump with an air stone to create bubbles and oxygen.
- Clean filters regularly to keep water clear and healthy.
Lighting Needs
Good lighting helps angelfish see their environment and supports live plants. It also shows off your fish’s colors.
| Type of Light | Recommended Duration |
| LED Aquarium Light | 8 to 10 hours daily |
| Fluorescent Light | 8 to 10 hours daily |
| Natural Light | Indirect sunlight only |
Heaters And Thermometers
Angelfish need warm water between 76°F and 82°F. Heaters keep the tank at the right temperature.
- Choose an adjustable heater with enough wattage for your tank size.
- Use a reliable thermometer to check water temperature daily.
- Place the heater and thermometer away from direct filter flow for accuracy.
Water Conditions
Setting up the right water conditions is important for your angelfish. Good water helps keep them healthy and active.
In this section, you will learn about the best temperature, pH, hardness, and water change routine for your tank.
Ideal Temperature Range
Angelfish live best in warm water. The ideal temperature range keeps them comfortable and supports their health.
Keep the tank temperature between 76°F and 82°F (24°C and 28°C). Use a heater to maintain this range.
Ph And Hardness Levels
Angelfish prefer slightly acidic to neutral water. The pH level affects their breathing and overall well-being.
Maintain a pH between 6.5 and 7.5. Water hardness should be soft to medium, around 3 to 8 dKH.
- pH: 6.5 – 7.5
- Water hardness: 3 – 8 dKH (soft to medium)
Water Change Schedule
Regular water changes keep the tank clean and remove waste. This supports angelfish health and water quality.
Change 25% of the water every one to two weeks. Use a water conditioner to remove chlorine and chloramine.
- Change 25% of water every 7-14 days
- Use water conditioner before adding new water
- Check water parameters often
Decor And Substrate
Setting up an angelfish tank requires careful choices for decor and substrate. These elements create a healthy and attractive home for your fish.
Good decor offers hiding spots and natural comfort. The substrate supports plant growth and helps keep the tank clean.
Choosing Safe Plants
Safe plants improve water quality and provide shelter. Use species that do not harm angelfish or change water chemistry.
- Amazon Sword: sturdy and easy to grow
- Java Fern: low light and slow growth
- Anubias: tough leaves and slow growth
- Cryptocoryne: good for hiding spots
- Vallisneria: tall and fast-growing
Substrate Options
| Substrate Type | Benefits | Considerations |
|---|---|---|
| Gravel | Easy to clean, good for plants | Can trap debris |
| Sand | Natural look, good for bottom dwellers | May compact over time |
| Aquarium Soil | Rich in nutrients, supports plant growth | Can lower pH initially |
| Peat | Soft texture, good for plants | May discolor water |
Creating Hiding Spots
Hiding spots help angelfish feel safe and reduce stress. Use decorations and plants to create these areas.
- Place driftwood or rocks with smooth edges
- Use dense plants like Java Fern or Anubias
- Arrange caves or ceramic pots for shelter
- Keep open swimming space near hiding spots
Selecting And Introducing Angelfish
Setting up an angelfish tank starts with choosing the right fish. Healthy angelfish live longer and adapt faster.
Introducing angelfish carefully helps them settle without stress or illness.
Choosing Healthy Fish
Look for angelfish that swim actively and have clear eyes. Avoid fish with torn fins or white spots.
- Check for bright colors and smooth scales
- Observe breathing; it should be steady and not rapid
- Choose fish that react to movement outside the tank
- Avoid fish that hide or float oddly
Quarantine Process
Keep new angelfish in a separate tank for two weeks. This stops disease from spreading to other fish.
| Quarantine Step | Action |
| Initial Observation | Watch fish for signs of illness daily |
| Water Conditions | Maintain clean water with stable temperature |
| Medication | Use treatment only if signs of disease appear |
| Final Check | Ensure fish eat well and swim normally before transfer |
Acclimation Techniques
Help angelfish adjust to new water slowly. Sudden changes can cause stress or death.
- Turn off the aquarium lights to reduce stress.
- Float the sealed bag in the tank for 15 minutes.
- Open the bag and add small amounts of tank water every 10 minutes.
- After 30–45 minutes, gently net the fish and place it in the tank.
- Do not add the bag water to the tank to avoid contamination.

Maintain stable conditions to avoid stressing the angelfish. Consistency is key for a healthy tank.
- Ideal pH level: 6.8 to 7.8
- Ammonia: 0 ppm
- Nitrate: Below 20 ppm
Common Problems And Solutions
Cloudy water is a frequent issue. Overfeeding and dirty filters often cause it.
Unhealthy fish behaviors like hiding or gasping signal tank problems. Quick action is necessary.
- Reduce feeding amounts to prevent waste
- Check and clean filters regularly
- Use water conditioners to clear the water
Tank Mates For Angelfish
Choosing the right tank mates for angelfish is important. It keeps your aquarium peaceful and healthy.
Some fish live well with angelfish, while others cause trouble. Pick tank mates carefully to avoid problems.
Compatible Species
Angelfish get along best with calm, medium-sized fish. Avoid very small or very aggressive species.
- Gouramis
- Corydoras catfish
- Platies
- Rainbowfish
- Ram cichlids
- Silver dollars
These fish share similar water needs and tank space. They usually do not bother angelfish.
Aggression Management
Angelfish can be territorial, especially during breeding. Watch for signs of aggression early.
Adding plenty of plants and hiding spots helps reduce stress. It lowers fights in the tank.
- Use tall plants for vertical space
- Add rocks or decorations as hiding spots
- Keep enough room for each fish
- Remove aggressive fish quickly
Avoiding Common Conflicts
Do not mix angelfish with fin-nipping or very fast fish. They can stress or harm angelfish.
- Avoid barbs and tiger danios
- Do not keep tiny fish like neon tetras
- Watch out for overly shy or aggressive species
- Separate fish that fight often
Careful planning helps keep your angelfish tank calm and happy. Observe your fish daily for changes.
