What should I keep in the balcony pool?

Hello, the swimming pool is overlooking. Koi fish, crucian carp or goldfish are the fish with good ornamental effect. Koi fish's broad back is like a colorful painting depicting ink painting. Carassius auratus has the title of Little koi fish, but it has no beard, and its figure and posture are not as good as that of koi fish, but it feels less blessed and generous than that of koi fish. The goldfish moves slowly, the quiet wedding dress swims slowly, and the plump posture even feels too exaggerated. ) It is suggested to raise koi fish, because I also raise koi fish. The golden crucian carp is too thin and the goldfish is not as lively as koi fish. Koi fish is not only round and plump, but also lively and cheerful, and has good communication with people. Moreover, it is a feng shui fish with a beard on its mouth and was regarded as a dragon in ancient times. Koi fish will write ink flowers on his body, China male turtles will lose ink when they grow up, and people will grow ink (moles). Turtle (ink turtle) occupies a high position in ancient divination and geomantic omen, and ink on human body also has many meanings.

I hope my answer is helpful to you.
