Customizable fish tanks may be made of high-quality glass, acrylic or other durable materials to ensure their sturdiness and durability. Such materials can withstand water pressure and minor collisions in daily use while maintaining good transparency. And users can choose the size, shape and even design style of the fish tank according to their needs and space size. This includes but is not limited to choosing a rectangular, round or irregular-shaped fish tank, as well as adding personalized decorative elements.
