Selling goldfish is an easy market to enter, but whether to make money depends on many factors. The first thing to consider is market demand. Goldfish has always been very popular in the pet market, so it has certain sales potential. However, the excessive reproduction of goldfish leads to oversupply in the market and fierce price competition. Also consider the cost of breeding goldfish, including feed, water quality maintenance, equipment and so on. If we can effectively control the cost and find a suitable sales channel, we may still make a profit. But no matter what goods are sold, there are certain risks and uncertainties. Therefore, if you want to enter the goldfish sales industry, you need to deeply understand the market demand, understand the breeding skills, have a certain sales plan and marketing ability, and have enough patience and determination to operate.
