Why Proper Aquarium Setup Matters

Setting up an aquarium correctly is the foundation of healthy fishkeeping. A poorly prepared tank can cause stress, disease, and early fish loss, while a properly set aquarium ensures:

• Stable water conditions
• Healthy fish growth
• Clear, odor-free water
• Low maintenance in the long run

Step 1: Choose the Right Aquarium Tank

Tank size plays a major role in fish health.

An ideal tank for beginners is 20-30 liters minimum
Bigger tanks are easier to maintain than small bowls.

Fish vise

• Betta Fish: Minimum 5 gallons (smaller bowls are not recommended)
• Gold Fish: 20 gallons for a fish, +10 gallons for each additional fish
• Guppy Fish: 10 gallons for a small group
• Tertra: 10–15 gallons for a school

Tips: Decide on the fish before buying a tank for it

Step 2: Select a Safe Location for the Aquarium

Place the tank:

• Away from direct sunlight
• On a flat, strong surface
• Near a power source
• In a low-noise, low-traffic area

Tips:

• Avoid kitchens and windows to prevent algae growth and temperature fluctuations.
• Use thermocol down the tank, if your not sure the tank is placed in flat surface.

Step 3: Clean the Tank (No Soap!)

• Rinse the tank with clean water
• Do not use soap, detergent, or chemicals

Tips: Unless the fish was affected by any decises, don’t clean the tank completly, if you did you might loose good organisam in the tank.

Step 4: Add Substrate & Decorations

Substrate gives a natural look and supports beneficial bacteria.

Popular options:

• Gravel (best for swallow fish like gold fish and koi)
• Sand (best for non-swallow fish, bottom-dwelling fish, and monster fish)
• Soil (for planted tanks)

Tips: Add aquarium plants, stones, or driftwood to create a natural environment to keep your fish happy.

Step 5: Install Essential Aquarium Equipment

Filter

Removes waste and keeps water clean.

Air Pump & Air Stone

Improves oxygen supply and water circulation.

Heater & Thermometer

Maintain temperature between 24°C–28°C for tropical ornamental fish.

Step 6: Water Condition It

• Use normal tap water (Unless cholarine is added)
• Add water conditioner to remove chlorine and harmful chemicals

Tips: To avoid the chlorine and harmful chemicals, use RO water or Drink water.

Step 7: Run the Aquarium (Cycling Process)

Before adding fish, allow the tank to run for 5–7 days.

This process:

• Builds beneficial bacteria
• Stabilizes water parameters
• Reduces fish stress

Tips: Never add fish immediately to a new tank.

Step 8: Properly Acclimate the Fish

• Float the fish bag for 15–20 minutes to match the temperature
• Add one cup of water from the tank to the fish bag every 20 minutes
• Drip the tank water into the fish bag using the tube in a slow release.

Step 9: Feed Properly

• Feed once or twice a day
• Only what fish can eat in 2 minutes

Tips: Overfeeding is the #1 reason for poor water quality.

Step 10: Maintain the Aquarium Regularly

Weekly Tasks

• Change 20–30% water
• Clean glass with an algae scraper
• Check the filter and equipment

Monthly Tasks

• Rinse filter media (in tank water)
• Inspect heater and air pump
