Things to Know Before Adopting a Fish and in the First Days

Bringing a new underwater friend home may seem like it just consists of setting up an aquarium and placing a few decorative plants from the outside, but it is actually the process of establishing a living ecosystem. Although fish cannot show affection directly like other land-dwelling pets, watching them has a proven calming effect on human psychology. However, to provide this peaceful environment, one must take a conscious step into the aquarium hobby. Before making the adoption decision, researching the biological needs of fish, such as water temperature, current intensity, and social compatibility varying by species, is the first and most critical step.

Aquarium Setup and Water Preparation Process

The most important element of an aquarium is not the living creatures swimming in it, but the millions of invisible beneficial bacteria. Therefore, it is essential to set up the aquarium at least a week before bringing the fish home, fill it with water, and run equipment such as filters and heaters to let it rest. Chlorine found in tap water has a toxic effect on fish; therefore, chlorine remover drops should be used during the water preparation stage, and the water temperature should be brought to the ideal living range of the fish species to be added. When choosing decorations, preferring natural rocks, roots, and live plants instead of artificial materials that can leach paint into the water helps the aquarium's water quality remain more stable.

Fish Acclimation to the Aquarium and First Feeding

When new fish arrive home in a bag, releasing them directly into the aquarium water can cause sudden temperature and pH shock, collapsing their immune systems. It is necessary to balance the temperature by letting the bag float on the aquarium water for about 15-20 minutes, and then slowly adding aquarium water into the bag to help the creatures get used to the new environmental conditions. Fish introduced to the aquarium may refuse to eat as they are usually stressed on their first days; this is normal, and overfeeding should be avoided. To prevent their digestive systems from getting tired, it is recommended to feed them in very small portions during the first 24 hours.

The main way to maintain long-term health in fish care is regular water changes. Changing about twenty percent of the aquarium water with fresh, rested water every week is effective in removing accumulated waste. When cleaning the filter, water taken from the aquarium should be used, and beneficial bacteria in the filter media washed with tap water should be prevented from dying. When sudden sluggishness in fish behavior, clamped fins, or changes such as white spots on the body are observed, water parameters should be tested and a professional opinion should be obtained if necessary. This hobby, pursued without forgetting the unique care requirements of each animal species, offers a healthy aquarium experience for many years.
