1. Skipping the Aquarium Cycling Process

Most beginners don’t know that an aquarium must pass through a biological cycling stage before adding fish.
Skipping this step can lead to toxic ammonia levels.

How to avoid it:

• Run the aquarium for 5–7 days with the filter on.

• Add beneficial bacteria (optional but helpful).

• Test water for ammonia & nitrite before adding fish.

This solves 90% of early fish deaths.

2. Choosing the Wrong Filter or Pump

Many beginners buy a filter that is too weak for their tank size.
A low‑quality pump fails quickly and leads to dirty, smelly water.

Best way to avoid this mistake:

Use a good internal filter and reliable pump from the start.
👉 JA brand filters and pumps are highly recommended — best quality + affordable price for beginners in Pakistan.
They are powerful enough to keep water clean and are easy to maintain.

3. Overfeeding the Fish

Overfeeding is the #1 cause of:

• Cloudy water

• Bad smell

• Fish sickness

• Algae growth

How to avoid it:

• Feed only what fish can finish in 20–30 seconds.

• Feed twice a day — not more.

Beginners often think more food = healthier fish, but it’s the opposite.

4. Choosing the Wrong First Fish

Some fish look beautiful but are not suitable for beginners or small tanks.

Fish beginners should avoid:

• Oscar

• Flowerhorn

• Arowana

• Large goldfish

Best first aquarium fish in Pakistan:

• Guppies

• Mollies

• Platies

• Tetras

• Zebra danios

• Shubunkin

• Koi

• Betta (single fish tank)

These fish are hardy and easy to keep.

5. Not Doing Regular Maintenance

Many new hobbyists forget that aquariums need regular cleaning and water changes.

 Maintenance tips:

• Change 20–25% water every week.

• Clean the glass once a week.

• Rinse the filter sponge in old tank water (never in tap water).

• Check the pump and filter flow regularly.
