Encouraged by the resilience of the second setup, which is 3 years old and still going strong, I decided to setup another similar one outdoor in the balcony. The bowl is ceramic and bigger than the glass bowl I already have. With more soil and larger volume of water, the eco system should be more stable. The only unknown is how well the fishes can withstand the winter months.
My plan is to plant something that will grow out of the water. I was hoping to find some mini water lilies, but have not yet able to source one that is small enough. So in the mean time I planted two types of plants that supposedly would grow out of water.
This picture also introduces the orchid I have in my home since 1999. It was a gift from the interior designer. After the initial flower bloom was finished, we just sort of kept it in the balcony and never paid much attention. My kids may occasionally water the orchid. And from my memory, the orchid had flower perhaps every spring.
When I setup the outdoor fishbowl, I just sort of reorganized the place so the orchid is one top, fishbowl at the bottom, with some extra space to keep other plants.
