I watched a video featuring an aquarium beautifully decorated with colorful coral. Inside lived marine fish such as the porcupine puffer, yellow tang, clownfish (famous from an animated film), and the blue-striped imperial angelfish—it was as if a slice of the ocean had been transplanted into the tank.
Curious about how sea fish could be raised in an aquarium, I looked into it and discovered it was far more complicated and demanding than keeping freshwater fish. First, an aquarium is needed, along with a sump tank—a separate tank that filters water through special media made for marine fish and pumps it back in. You also need a salinity meter, a submersible heater, a thermometer, lighting, a wave-making motor, an oxygen generator, and marine salt. Even after setting all of this up, you must wait several weeks—sometimes up to two months—for the water conditions to stabilize enough for the fish to adapt. Once the fish are added, you must carefully monitor whether they are eating well, and meticulously manage the salinity, water quality, and temperature to prevent issues like ich, bacterial infections, and parasites. In short, you must replicate the exact environment and conditions of the ocean.
Reflecting on this, I was once again struck by the wonder of the life system that sustains living beings all over the Earth, ensuring they thrive in their proper environments. People often sum it up as “the laws of nature,” but I know the truth: The invisible love and tireless care of God Elohim are intricately woven into all creation.
