Does it take a long time to feed the high-backed arowana?

I don't think it's necessary. Arowana can't turn on the light when sleeping. It is enough to turn on the light around 7 pm for 3~5 hours. Choose white light, and put a whiteboard on the back of the fish tank, which is helpful for coloring.

If the color is finished, it is suggested to change the black background and adjust the luster with red light.

Driving for a long time is easy to cause short circuit, which is a bit dangerous. Arowana always wags its tail, and it is not good to get water and light the wires inside.

I hope it will help the landlord.
