It’s pretty good. Apart from ordinary fish tanks for beginners, Sihai’s tanks are pretty good. They are more professional tanks suitable for raising arowanas and are cost-effective. The better one is the colorful butterfly, but the price is too high and I can’t afford it. . . . Never buy an ordinary fish tank that costs more than 2,000 yuan. The width of the fish tank is too narrow and ugly, so it is not suitable for raising arowana. Personally, I prefer this kind of fish tank with no borders at the four corners, which is better for viewing.
