It is appropriate to raise fish at home.

Read the answer above. If you keep a silver dragon in your fish tank, I would say that one is not enough. Your fish tank is too small. I have kept silver dragons for several years, but small tanks will affect the growth of silver dragons. If I raise it well, it will grow to about 40-50cm after one year, and it will not fall into your jar after one and a half years, and it will eventually become ugly. If you must keep a silver dragon, it is recommended to keep only one, preferably mixed with parrots. It is still recommended to change the value-added tax. Finally, if there is no even number of arowana, it is usually odd.
