Regular water changes are crucial in keeping the environment healthy. I found that using a water conditioner helped eliminate harmful chemicals from tap water.

Setting Up the Aquarium

Setting up my aquarium was an exciting process. I added substrate, decorations, and plants to create a natural habitat. I made sure to rinse everything thoroughly before adding it to the tank. Once everything was in place, I filled the tank with water and let it cycle before introducing any fish.
