1. Reason: When the water quality in the fish tank is too poor, guppies will have adverse reactions, causing congestion on their body surface, which is the erythema we see.
2. Treatment method: Change the water for them in time, and this phenomenon will gradually disappear. In general, change their water once a week. If there is a filter in the fish tank, you can extend the water change time for them, and it is also possible to change the water once a month. However, the amount of water can not be changed too much each time, and a quarter of it can be changed each time.
1. Cause: When guppies suffer from red skin disease, you can see that they have red spots like bleeding. Red skin disease is infectious, so they need to be quarantined.
2. Treatment method: fish out the guppies with red spots on their bodies, soak them in 3% coarse salt solution, and sterilize their body surfaces. Then pour out the water in the original fish tank, soak the fish tank with permanganate acid and alkali for about half an hour, and replace it with new water with little difference in water quality.
1, reason: many people in the process of fish farming, like polyculture. But in the process of polyculture, they often only pay attention to the beauty and forget the temperament. When guppies are mixed with ferocious fish, they are easily bullied, resulting in red spots on their body surface.
2. Treatment method: fish out the guppies and feed them separately in water with a temperature of 28-30 deg C and a PH value of 6.5-7.5. Then put the fish tank in a quiet place and let them rest and recover.
