Arowanas are famous for their gorgeous colors and graceful postures. Some golden and red varieties are praised as the best aquarium products because they are said to have the effect of exorcising evil spirits and calming down the house. Their prices can easily reach tens of thousands or even hundreds of thousands. It is worth mentioning that Arowana has long been listed as a first-level endangered species by the Convention on International Trade in Species, and trade is strictly prohibited. At present, it is still difficult to artificially breed this fish, and most of the fish raised in the country are smuggled. There is no scientific reason for using foreign fish to sell domestic homes. As an aquarium enthusiast, I appeal to everyone not to buy and raise this kind of rare fish, which will stimulate smuggling activities in disguise, and use your own conscious actions to support environmental protection.
