If it doesn't match, the arowana won't die or be seriously deformed because there is no heavy wave pump, but it is definitely better to match it, which can increase her exercise. Some people say that the domestic arowana has too little exercise, a small jar, no world and no need to chase its prey, so it doesn't move. Plus it eats well, with high protein and fat, so some people think it has something to do with immobility. No matter how much the heavy wave pump can relieve the effect of eye drops, it is an unchangeable natural law for any animal to exercise more. So whether to add or not, you can consider whether you are willing to bear the consumption, and adding it will definitely be beneficial. However, I feel that I don't want arowana to exercise. After all, not everyone has a dragon. But arowana has a hobby of drowning and swimming, which is more in line with the laws of nature.
