Raising goldfish is no more disgusting than other types of fish. In fact, grass goldfish is one of the very easy pet fish to keep, and its basic maintenance needs are similar to other fish species.
But it is not recommended for new aquarists to raise very small grass goldfish from the beginning, which are similar to feed fish. Because the quality of this kind of grass goldfish is really poor, due to long-term extreme hunger, most of these feed fish were already extremely thin by the time we bought them home. Their resistance to various diseases can be said to have been completely lost.
