If ornamental fish do not want to be raised, it is best to sell them or give them away. On the one hand, many ornamental fish belong to alien species and can not be released at will. On the other hand, ornamental fish adapted to human care, lost the ability to prey, and could not live in the water. In addition, some ornamental fish can be eaten, but it is better to determine the species before eating, check whether there is poison.
1. Scavenger: Scavenger is a common tool fish, and it is also an invasive alien species, so it cannot be released. Many people think that the vitality of the scavenger is tenacious, dried as long as there is water can live, in fact, this is not the case, as a tropical fish, its adaptability in the wild is not very good, but even so can not be released.
2. Gar: As an alien invasive species, Gar has caused harm to the ecological environment in many parts of our country, so it must not be released. And this kind of fish has certain aggressiveness, it is more ferocious carnivorous fish, once released, it will easily dominate.
3. Goldfish: As a traditional ornamental fish in China, goldfish has a long history of cultivation, and there are many varieties. But among the many breeds, only a few can adapt to the environment with poor water quality, most of them are very delicate, can not live at all after release, and will become a good meal for other animals.
