Adult male guppies can grow to 3 to 4 centimeters, the female fish's body length is about 5 centimeters. If the fish don't grow to this length, it may be due to both space and nutrition. If the tank size is too small, or the breeding density is too large, many fish are crowded together. At this time, the space is very narrow, and the fish's swimming is limited, which will inhibit its growth to a certain extent. On the other hand, the growth of fish is unlikely to be caused by malnutrition. The nutritional content of food can not meet the nutritional needs of its growth and development. Without adequate nutrient supply, the growth and development of fish will slow down. After the growth period, it will no longer grow up. At this time, there will be a phenomenon that the fish will not grow up.
1. Temperature: Control the temperature in its most suitable range, that is, between 22 ℃ and 24 ℃. Warm environment will improve the activity of enzymes in its body, so that fish can fully absorb nutrients and promote growth and development.
2. Water quality: It is also essential to provide a clean and suitable environment for fish to grow. Regulate the PH value of the water between 6.5 and 7.5, and keep the water quality clear and the oxygen content sufficient.
3. Feeding: Feeding it mainly with live bait. It can be fed with protein-rich foods such as shrimp, tubificid worms and water fleas. Growing fish need to be fed 2 to 3 times a day, each time to ensure that it is full.
4. Space: to provide enough space for the fish to swim freely. A certain amount of activity every day can promote growth and development.
