1. The characteristics and selection of the parent fish  The small fish bred from the parents of Huajiao and Pearl Luohan will basically inherit the characteristics of their parents, but the Jinhua variety The bred young fish are very different from their parents, and they are not exactly the same in appearance, so it is very difficult to get a fish with a golden flower head and a more outstanding appearance. In addition to the consideration of appearance, the health of the fish is also very important. If one of them is sick, the eggs it lays will be infected and affect the hatching. Small fish will inherit the traits of their parents and vice versa. 2. Characteristics of Luohans Female Luohans and male Luohans are very different in appearance and body size. Basically, males are much larger than females. Fish take a long time to mature, and males are much older than females when they are capable of breeding. 3. Care of small fish When the small fish grow to 2 or 3 cm, they can be changed to red nematodes, or minced shrimp, nematodes are better. As for the larger juveniles, they can be fed artificial sweat castles and minced live bait. 4. Nursing and feeding of small fish at various stages Generally, a good variety of Luohan basically has some characteristics of adult fish in 2 to 3 months. The lines, spots, and even lychee heads, water heads, and pearl points have already appeared. This is the reason why we call good varieties of small fish, and the price must be very expensive. Finally, I hope that all the Arhats that you breed by yourself are water heads.
