How to raise green puffer fish?

Green puffer fish (green puffer fish), also known as submarine fish, golden doll, doghead, chicken bubble fish, etc., belongs to the family Carpinidae ornamental fish, can be called spotted green puffer fish, can grow up to 17 centimeters in the wild, but it usually grows less than that in the aquarium. Most of the fish sold on the market are about 5 centimeters. Now the tropical ornamental fish is very popular. Let's take a look at how the green puffer fish is raised.

What do green cuttlefish eat?

Green cuttlefish do not choose to eat, can swallow small fish with large mouth, and should not be mixed with other small fish. There are individual differences in food preferences. Generally acceptable foods include nematodes, frozen red worms, clams and shellfish, frozen shrimp, frozen fish, dried shrimp, bread worms, snails or snails, live shrimp, live fish and so on.

How do green cuttlefish reproduce

The green puffer fish with a body length of about 7 cm is the parent fish, and it is not easy to distinguish between female and male fish, but the body color of the male fish in estrus is brighter than that of the female fish, and the center of the outer edge of the caudal fin appears sharp, while the female caudal fin is still round, and the ends of dorsal fin and anal fin are more round and obtuse. The length and size of male and female fish are similar, but the abdomen of female fish is enlarged. The water temperature of the spawning box should be kept at 25-26 ℃, the water quality should be slightly acidic, the hardness should be 6-7 degrees, and the chrysanthemum plants should float on the surface. A female fish can lay more than 100 eggs and then fish out the parent fish. The eggs are relatively large, the hatching period of fertilized eggs is longer, and it takes about 12 days to hatch larvae. Small green cuttlefish can prey on live baits such as harvest insects and water flea larvae.

How to raise green cuttlefish

The main results are as follows: 1. Green puffer belongs to the family Fugu, which has the ferocious characteristics of the family Fugu, so it can not be mixed with green cuttlefish. Green puffer has a large food intake, and will actively attack other fish, resulting in monoculture and low density. There should be more water plants in the tank, and the filter flow must be slow, do not like the strong flow, the filtration system can not add activated carbon, like weak alkaline water, activated carbon will reduce the PH value. To observe the color of the belly at any time, this is the most intuitive way to check the health of green puffer fish.

2. Lvhe mackerel has the habit of reproductive migration, ferocious and timid, and often kills each other when the living environment is bad (such as insufficient bait and high culture density), especially in the seedling breeding stage. The structure of its esophagus is special, which makes the green puffer inhale air and water when it is attacked or frightened, so that the chest and abdomen are enlarged like a ball, and the small thorns of the skin stand erect and pretend to be dead on the water surface, so as to defend themselves. After being safe, quickly discharge the air and water in the chest and abdomen and swim quickly.

3. Green cuttlefish have the habit of gnashing teeth and will make a "goo" sound after being arrested. Under natural conditions, it mainly feeds on aquatic invertebrates and other animal and plant baits. It is an omnivorous fish that is partial to animal food. Under artificial feeding conditions, it can also eat artificial compound feed after domestication.

4. The water temperature of green puffer fish culture should be kept above 18 ℃, the feeding of 16 ℃ decreased obviously, the feeding temperature of 11 ℃ stopped, and the most suitable water temperature for growth was 25 ℃ ~ 28 ℃. There is a high requirement for dissolved oxygen in water, which requires that the dissolved oxygen in pool water is more than 5mg / L, when the dissolved oxygen in pool water is 3.0 mg / L, it will float slightly, and when the dissolved oxygen in pool water is less than 1.5 mg / L, green puffer will die if it is not treated in time. The pH value of pool water should be 7-8, and the transparency of pool water should be 40 cm.
