迎接黑龙鱼前需要了解的7件事

1. 1Needs a Large Tank

   Black Arowana can grow to nearly 90 cm, so a spacious tank with generous length and width is essential in the long run. Plan your tank size with the adult fish in mind from the start.

2. 2Watch for Jumping

   Arowanas live near the water's surface and can leap suddenly when startled. A secure, tightly fitted lid with no gaps is a must.

3. 3Color Changes With Age

   Juveniles show a black body with yellow stripes, which gradually shifts into a shimmering blue-purple sheen as they mature. Watching this transformation is part of the appeal.

4. 4Demanding Water Care

   As a large fish, it produces a lot of waste, so a powerful filter and regular water changes are essential. It's also sensitive to sudden shifts in water quality.

5. 5Best for Experienced Keepers

   This species calls for handling experience due to its size and temperament. First-time large-fish keepers should build up knowledge and equipment before bringing one home.

6. 6Choose Tankmates Carefully

   Smaller fish that fit in its mouth may be preyed upon, so tankmates should be of similar or larger size. Some individuals can be territorial, so layout matters too.

7. 7Plan Your Space in Advance

   A large tank is heavy, so check the floor's load capacity and delivery access beforehand. Since this is a long-term companion, plan the placement and maintenance routine too.
