Hydroponic plants are a great choice for many busy flower lovers, and when the weather is hot, having some hydroponic plants at home can even
make you feel more refreshed and cool. Placed in the office, they also look more elegant and highly ornamental
! But some flower lovers are not satisfied with just that - they even keep two small fish in the hydroponic vase! How do they do it? Let's take a look~

Flowers and fish living together
”
Many plants can be grown hydroponically, and any with well-developed root systems can be. Such as
foliage plants like Alocasia (dumb cane), spider plant, arrowhead plant, lucky bamboo, pothos, pennywort, Tradescantia pallida, and so on are all excellent hydroponic plants. Many vegetables and fruits can also be grown hydroponically, such as potatoes, radishes, taro, and more - a real sight to behold!
Hydroponic plants can be kept with fish, and most people use transparent glass fish tanks, where the plant roots and small fish complement each other in motion and stillness, creating a unique scene. However, there are some things to pay attention to during care, otherwise the small fish you keep can easily die.
Plant selection
First of all, the hydroponic plants must be non-toxic, otherwise the small fish will
bite the roots and be poisoned. Plants like pothos, pennywort, Tradescantia pallida, sea onion, and snake plant are all excellent hydroponic plants that won't harm the small fish.
Fish selection
Generally, hydroponic vases are not large, so the fish you choose should basically be small species - if they're too big, it's just mistreating
the little fish,
and a body length of no more than 3 cm is ideal.
The quantity also can't be too many - after all, the space is small, and too many can easily lead to oxygen deficiency. Generally 1-3 fish.
Choose species that are relatively easy to keep alive - tropical fish, ornamental crucian carp, such as guppies, swordtails, black mollies and other small tropical fish. Goldfish are not recommended, as they die especially easily.
In short, small, easy-to-keep fish with low oxygen demands are the first choice for mixing with hydroponic plants.
Feed less
Feed as little as possible, because feeding easily causes fish food to pollute the water quality, affecting
the growth of the plants and small fish.
Many small fish can survive just on the plankton in the nutrient solution, so feed as little as possible. If you do feed,
it's best if the food is completely eaten within 3-5 minutes of being sprinkled in. You can combine feeding with water changes - change the water after feeding is complete.
Water changes
Usually prepare some
extra water and let it sit in the sun for 1-2 days before use.
Generally, in spring and autumn you can change the water once every 5-7 days, in summer once every 2-3 days, and in winter, when fish are less active, once every 1-2 weeks.
When changing the water, let the water temperature be close to room temperature, to avoid the small fish getting sick from too great a temperature difference - especially in winter and summer, when water that's too cold or too hot is not good.
Each time you change the water, you can keep
half
of the old water, pour out the feces and debris at the bottom of the vase, then put the poured-out old water and the prepared new water back in. This can both improve the fish's adaptability, and the fish feces in the water can also provide nutrients for the plants. Change all the water with new water once a month.
Don't add nutrient solution
When changing the water for hydroponic plants kept with fish, there's no need to add nutrient solution - some nutrient solutions are harmful to fish, and they also easily worsen the water quality. For ordinary hydroponic plants, you can spray foliar fertilizer to supplement nutrients.
