Can fish tanks keep 19 fish?

From the point of view of feeding, it can be raised, but it is restricted by many factors such as fish tank specifications, feeding types and equipment.

From the perspective of geomantic omen, 19 is a number of bad luck (representing adversity, ups and downs, weakness, disease, difficulties, disasters, etc. ).

From the actual situation, it is better to feed the fish first and then talk about the relationship between numbers and fortune. A wise friend must support nine, saying that gold and water are born together. As a result, one or two people always die every few days, and I don't know if there will be gold.
