1. Reason: When the water quality is too poor, the bacteria in the water will multiply in large numbers. When they multiply to a certain number, they will infect the weak guppies and make their bodies rot and white.
2. Treatment method: First, check whether the filtering equipment is not suitable, and replace the equipment with appropriate power in time. Then change the water in the fish tank. Do not change too much water each time to avoid sudden changes in water quality. Generally, a quarter of the water can be changed each time.
1. Reason: When the feeding density is too high, they will rub against each other, resulting in body surface damage. In addition, they will fight for their living space and hurt their bodies. At this time, some bacteria will enter their bodies along the wound, causing them to turn white and rot.
2. Treatment method: First fish out some guppies and put them in a new fish tank with similar water quality, then add oxygen to the original fish tank to supplement oxygen for them, and finally raise them in a quiet place to let them recover slowly.
1. Cause: When guppies are infected by Saprolegnia, their bodies will be covered with white hair at the beginning. If they are not treated in time, they will gradually become white and rotten.
2. Treatment method: fish out the diseased guppies to avoid the spread of Saprolegnia to infect healthy fish. The diseased guppies were then placed in a low-concentration potassium permanganate solution and treated with a medicated bath.
