Build a false mountain fish pond on the balcony

Quick answer：

Building a false mountain fish pond on a balcony requires careful planning and design. The pond should be small enough to fit the space but large enough to accommodate the desired fish species. It's important to consider the materials for the pond, such as tiles or concrete, and the plants that can be used to create a natural-looking environment. Additionally, proper filtration and aeration systems must be installed to maintain water quality and the health of the fish.
