Red tailed crown fish can distinguish male and female by observing their appearance. Males are usually slightly larger and more brightly colored than females, and the ends of their dorsal and anal fins are longer. If you want to breed, you need to let them pair themselves first. Then prepare a breeding tank away from light, put the matched parent fish into it, control the water temperature between 27-29 ℃ and wait for them to mate and lay eggs. Small fish can be fed after hatching for 5 days. 1、 How do red tailed crown fish divide male and female? It's relatively simple for red tailed crown fish to separate male and female. The male is larger than the female, and the color is more bright. In addition, the ends of male dorsal fin and hip fin are longer, and the anal process of female fish is more round and blunt. 2、 How to breed red tailed crown fish 1. Preparation of fish tank: before breeding, red tailed crown fish needs to prepare a breeding tank. The specification of the tank is 50 * 50 * 40. Inflation and filtering equipment should be installed inside. At the same time, newspapers should be pasted around to shade the light in the tank. The water temperature in the cylinder is controlled between 27-29 ℃ and pH is about 7.
2. Self pairing: red tailed crown fish usually need to pair and reproduce by themselves. If they are paired manually, it is often difficult to succeed, and the female will be bitten by the male. Usually observe a close pair of parent fish in the fish species, take them out of the tank and put them in a specially prepared tank.
3. Mating and spawning: after the red tailed crown fish enters the breeding tank, it will mate and spawn. After the female spawns, the male will fertilize it. Because parent fish have the habit of protecting their eggs, they don't have to fish them out. They can also stir the water body with their fins in the tank to provide oxygen for the eggs, which is conducive to the hatching of fish eggs.
4. Larval maintenance: usually, the fertilized egg hatches a small fish after 72 hours. A few days ago, it can absorb the nutrition in the yolk sac, so it doesn't need to eat. After 4 or 5 days, it will start feeding. Usually, it is fed with harvest insects and gradually transition to other foods. （GongWeiHuangGuanYuZenMeFenGongMu，RuHeJinHangFanShi）
