? The release of guppies will not lead to biological invasion, because it is difficult for them to breed in large quantities in the wild of our country. First of all, most of the water temperature in our country is not suitable for the survival of guppies. They are tropical fish, and their favorite water temperature is between 22-26 degrees Celsius. The temperature in winter in our country is low. In wild rivers and lakes, the water temperature will not always be around 22 degrees Celsius. In addition, guppies are small and gentle, and it is difficult to catch food in the wild. Although they can eat mosquito larvae, other larger fish may also eat them. Even if they can survive in the wild, the number of reproduction and the survival rate of small fry are relatively low, so the release of guppies will not cause biological invasion.
if guppies can't be raised? Guppies not only have a large number of reproduction, but also have a relatively high frequency of reproduction, so every time they breed, they will exert pressure on breeding. Family breeding, the general space will not be particularly large, guppies breed in large numbers, the space of the fish tank will be insufficient. Breeders can choose to give the breeding guppies away or consult their local aquariums about recycling. Or use small fry as feed to feed big fish.
