The colorful old man fish refers to the immortal fish that does not grow up. They are small, with prominent eyes and abnormally pointed mouths. There are many reasons for this situation. First of all, from a genetic point of view, some angelfish are genetically deficient, and they are prone to the risk of growing into old fish. Secondly, from the later diet, if the nutritional intake is not balanced, this situation will also occur. Finally, if the breeding density is too large, some fish activities are not sufficient, which will also lead to the problem of old fish. In addition, if the fish is sick for too long, it is also prone to this situation.
1. Feeding: Follow the principle of eating small meals, feeding three times a day in the morning, noon and evening. Every meal should be reasonably matched, such as frozen red worms, nematodes, hamburgers or pellets. The feeding amount can be controlled within five to ten minutes.
2. Activity space: flow hole can be arranged manually, so that that colorful old fish can be pus to move in an artificial mode, and the exercise amount is increased. At the same time, it is also necessary to control the breeding density reasonably, generally ensuring that an adult fish has at least 10 liters of swimming space.
3. Aquaculture observation: need to observe the state of angelfish in time, there is a disease need to be treated immediately.
