Guppies are rolled up and die when they are born. This is because when guppies are pregnant, if the water temperature is unstable, the water quality is poor, or there are no nutrients or other adverse environmental factors, the fertilized eggs will develop poorly or have chromosomal abnormalities, and they will not hatch. The fry that come out will roll into a motionless ball and die.
Guppies require certain temperature and water quality conditions when hatching. If these conditions are not met, the hatched fry will roll into a ball and die. During the hatching and growth process, if guppies lack sufficient nutrition or are affected by disease, they may easily roll up into a ball and die. In summary, the reason why guppies roll up in a ball and die may be due to environmental factors, malnutrition, disease and other factors. Therefore, when breeding guppies, you need to pay attention to providing a suitable environment and feeding< span style="font-size: 1em;">Raising conditions to ensure the health, growth and development of guppies.
