I have loved fish since I was a child. When keeping fish, the most important thing is to create a good and safe environment for them. When I set up my first fish tank, I learned a lot. Today, I want to share my experience with you about how to easily and properly set up a fish tank. This will be very helpful for those who are just starting.
Choosing the Tank or Aquarium
You need to decide the tank size based on the type and number of fish. I got a 40-liter tank for my small goldfish and other small fish, which was quite suitable. Make sure to clean the tank well before use so there is no dirt or chemicals inside.
Personal Tip: I first bought a big tank but a medium-sized one is enough for small fish. So choose the size according to your fish count.
Filter
Without a filter, the water in the tank gets dirty quickly, which is harmful to fish. I use a top filter that removes waste and helps healthy bacteria grow. This is absolutely necessary for the health of the fish.
Using a Heater
If you want to keep tropical fish, a heater is very important. I use an automatic heater that keeps the water at a set temperature by itself. This keeps the fish healthy and active.
Oxygen Pump
Fish need enough oxygen to survive. I use an oxygen pump that circulates water and supplies oxygen, keeping the fish calm and healthy.
Water and Water Conditioner
Always test the water before putting it in the tank. If the tap water has chlorine or other harmful chemicals, use a water conditioner. I personally have had very good results using this.
Substrate (Gravel or Sand)
Putting some gravel or sand at the bottom of the tank creates a natural environment for the fish and helps bacteria grow. I also added some artificial plants that give the fish places to hide.
Preparation and Waiting Before Adding Fish
After filling the tank with water and turning on the filter, heater, and oxygen pump, I waited at least two weeks. This allows good bacteria to develop which creates a safe environment for the fish. This is my most important tip and everyone should follow it.
Care When Bringing Fish Home
Bring the fish home in a plastic bag. When you get home, float the bag half-submerged in the tank water for 20 to 30 minutes so the fish can adjust to the new environment. Then gradually mix the bag water with the tank water before releasing the fish. I have reduced my fish’s stress a lot by following this method.
Regular Maintenance
Change 20 to 25 percent of the water every week.
Clean the filter foam with water once a month but do not use detergent.
Feed the fish regularly and check the water quality.

Conclusion
Setting up a fish tank is not difficult. With a little patience and care, you can create a beautiful environment. My goldfish are now like family members. Spending time with fish is a source of peace for me. You can start with a small aquarium too. I believe fish will bring you lots of happiness.
