1. Water temperature

Silver arowanas have relatively high water temperature requirements. It is recommended to keep the temperature at 23°C to 28°C year-round, and keep the pH between 6 and 8 to prevent excessive acidity. In addition, seasonal changes will cause temperature differences, so remember to adjust the temperature of the fish tank.

2. Lighting

Control the lighting for silver arowanas at about 8 hours per day. Without enough light, the silver arowana's back will become dull and lusterless. Silver arowanas are silver all over and do not require color enhancement, so a trichromatic white tube is sufficient. If conditions permit, try to let the silver arowana absorb natural light. If only lamplight is used, the back of the silver arowana may turn black.

3. Water changes

Water needs to be changed about twice a week, with about 30 percent changed each time. In addition, the fish tank should be wiped and washed frequently to keep it clean and free of scale, and food residue should be cleaned up promptly to avoid polluting the water quality, breeding bacteria, and causing illness in the silver arowana.

4. Feeding

In addition to special arowana feed, they can also be fed fish, shrimp, and so on to increase nutrition.

5. Mixed keeping

Silver arowanas are large and relatively ferocious, so keeping them mixed with other fish is not recommended.

Arowanas are relatively large and grow quickly, so when preparing a fish tank, it is best to choose a larger one.
