? The breeding of goldfish needs lamplight, the best light is sunshine. Sunlight can not only promote the absorption of calcium by goldfish, but also make the color of goldfish's body surface more beautiful. At the same time, ultraviolet rays in sunlight also have bactericidal effect, which can kill bacteria harmful to goldfish in water to a certain extent. However, if the goldfish is exposed to the sun, it must not be exposed to the sun at noon when the sun is strong, otherwise it is easy to prevent the goldfish from being harmed. If the fish tank does not receive sunlight, lights can be used to illuminate them.
for goldfish? When the goldfish bowl can not be illuminated by sunlight, it is better to choose a full-spectrum lamp close to sunlight. For example, metal halide lamps and led lamps are good choices. When choosing the lamp, we must pay attention not to choose the red lamp, which has no other function except to make the goldfish look better temporarily. When
using light instead of sunlight to illuminate the fish tank, choose the appropriate wattage lamp according to the density of goldfish. At night, it is best to turn off the light, so as not to affect the normal rest of the goldfish. The light used in the fish tank should not be too strong, otherwise it will affect the health of the goldfish, and even make the goldfish blind.
