High-end, I know butterflies, very high-end.
Ordinary, Sensen and Minjiang, the finished cylinders of these brands all have dragon cylinders.
In addition, lovely jars have been very popular recently, and we have opened a new shop here. But there are also many negative news about this brand on the Internet. If you have money to buy a lovely jar, you might as well add some money to buy a butterfly. However, I have been to a physical store. Lovely cylinders are well designed.
Free water change in finished product cylinder? Faucets and drains? God, think of it as a swimming pool. Tap water must be dried or dechlorinated before use. Put water directly into the tank with the tap, and the arowana can eat in the tank. Don't be lazy when changing water, use a vat or basin.
Length and width, not very harmonious. Because you raise arowana. Arowana is very long, so there is room for fish to turn around, and the width is preferably above 50. So the dragon tank is very wide. If you want someone to order it, you can go to the fish shop to see the size of the finished cylinder for reference.
