The Underground Fish Pond

I saw a unique fish pond design. The fish pond construction is underground. This is how he built his fish pond. The owner shoveled a 1.5 meter deep by 3 meter long and 2 meter wide fish pond at his garden. The size was meant to maximize the space between his house and the gate on his garden. He then covered about ¾ of the top with concrete and topped it with garden soil and grass. From the top, one can only see a 2 meter long by 0.75 meter wide fish pond, most of it was underground. For the fish pond filters, it is perched on a ledge the owner made. Colored rocks adorned the bottom complementing the colored fishes. Colored Tilapia was his choice of fish. It is a hardy fish that tolerates a variety of water conditions. It grows and breeds fast. The fry were immediately separated by a net to prevent it from being eaten by the larger fishes. The owner later decided to discard the net because it doesn’t look good on the pond. What he did was rearrange the rocks in such a way that it will provide shelter for the fry until it grows big enough to survive with the larger fishes.

The fish pond design is a space saver. People can walk along the roof of the pond and even put potted plants there. Treat it like it is part of the garden soil around it. The fishes on the other hand would have a lot of space to swim about. The roof provides shading that helps prevent blooming of algae.

Due to the size of the pond, it can contain bigger fishes like the arapaima, or koi that grow up to a meter long. In the meantime, he just enjoys looking at his colored Tilapia in the underground fish pond.
