1. Reason: During the seasonal alternation, the water temperature is neglected and the thermal insulation measures are not taken, which leads to the low water temperature. When changing the water, the temperature of the new water was too low, and the new water was not heated, so it was poured directly into the fish tank. The temperature in summer is too high to cool down in time. The high and low water temperature can easily stimulate guppies and cause Saprolegniasis.
2. Treatment: When the water in the fish tank is too low, the heating rod should be turned on immediately to raise the temperature. When changing new water, if you choose cold water, remember to pour in some hot water to increase the temperature. When the temperature is high in summer, it is better to use cold water to cool down. Pay attention to the weather forecast in time. When the temperature is low, cover the fish tank with insulation film.
1. Reason: When the female guppy gives birth, the amniotic fluid will flow into the fish tank. Amniotic fluid is easy to deteriorate in high temperature environment, and bacteria adhere to the skin of guppies, causing Saprolegniasis.
2. Treatment method: After the guppy gives birth, it is better to fish the big fish and the small fish into the breeding tank with changed water, and the water temperature in the breeding tank should be consistent with that in the original tank.
1. Reason: In the process of fishing and transporting fish, the skin of the fish is scratched. At this time, the water quality is poor, and the wound is easily infected by bacteria, which leads to Saprolegniasis.
2. Treatment: Soak the guppy in two millionths of potassium permanganate solution and one hundredth of salt. The time can be controlled within 20 to 30 minutes, which can effectively control the growth of the water mold.
