Green moss is not necessary to raise Lanshou goldfish, and breeders can choose whether to raise or not according to their own preferences. The advantage of breeding green moss is that Lanshou goldfish can eat fresh plants at any time, because green moss can make their body color more bright, and green moss contains more trace elements, which can keep nutrition balanced, so there is no need to deliberately feed plant feed at ordinary times. The disadvantage of breeding green moss is that the growth speed of green moss is relatively fast, which will absorb a lot of nutrients in water, which is not conducive to the growth and development of goldfish. Green moss is not necessary to raise, and breeders can decide whether to raise green moss according to their actual situation or the situation of fish tanks.

To raise green moss in fish tank, as long as they are provided with proper light, they can grow rapidly, and there is almost no need to raise them specially. Because green moss grows fast, breeders should clean it regularly to avoid them growing too fast and affecting the growth and development of fish. In addition, green moss depends on nutrients in water to survive. If there are too many green moss, the nutrition of other plants and animals in water will decrease, so we should pay attention to controlling the number of green moss at ordinary times.
