Territorial nature
Feeding difficulty
The water temperature is 22-28℃
Hardness 6-9dH
Ph value 7-8
Love carnivores, usually frozen or fresh blood worms, earthworms, shrimps, shellfish, crabs, squid and snails are their favorite foods. Remember not to feed too much at a time, or constipation will easily lead to death. They like a slow and quiet environment now. They usually hide during the day and come out to play in the morning and evening. They are very active. .
Water temperature: it is fixed at 27℃ with a heating rod, but it will rise to 30℃ in summer, so the author searched the literature on the Internet. Literature shows that the temperature is between 22-29℃ and the pH value can be between weak base and weak acid. The dolls live well in this range.
Food: 1. Frozen red worm
2. Live worms: but pay attention to bacterial infection.
3. Live red worms: You can buy them in fishing shops. The author says that dolls seem to like to eat.
4. Corn flakes: The author ignores them and does not discuss them.
5. Snail: The author said that his doll doesn't seem to like eating very much.
Doll's name: Many countries have different names, such as the Japanese "Abeni Puffer" and the British "Puffer Puffer".
Gender: Men and women can be divided into the following points:
1. The male's abdomen has brown stripes (see picture), but the female doesn't.
2. When the male has courtship behavior, this line will thicken and become dark brown.
3. Men have wrinkles behind their eyes (the author says that both of his men are like this, but women are not, but it may be an individual case).
4. Females are rounder than males during spawning.
Birth: 1. It was born about five months after the author bought them, from April 1999 to September 1999).
2. Males will fight with other males during estrus, so the author isolates them (one male and two females).
Behavior during courtship: 1. The male will snuggle up to his mother and kiss her body when chasing her. Females usually swim slowly, while males wriggle.
Sometimes the female will swim away from the male, but the male will attack it and occasionally bite it.
3. Sometimes the female will not leave the male, the male will be next to the female, and the female will enter a narrow place, such as the corner of the jar, or a cool place.
When this behavior happens, males will attack other aquarium members (regardless of gender).
When a male and a female are put in the same jar, the male will courtship each female (my comment: it is obvious that it is not monogamous).
6. When a male and a female are courting, the other female will hide behind the plant.
Oviposition: 1. When the mother decides to lay eggs, the male will approach the mother, while the female and male will slightly shake their bodies for about 5~ 10 seconds, which is laying eggs and releasing sperm.
2. Most females lay eggs in moss or moss, and rarely lay eggs on leaves.
After laying eggs, the males will drive the females away.
Other key points: 1. Courtship occurs almost every day during the spawning season.
2. Courtship and spawning in the afternoon.
Behavior of male dolls in estrus;
1. There will be a vertical brown line in the abdomen.
2. The body looks beautiful, and the body is not as round (pointed) as the mother.
Almost all the color blocks on the back have faded, and the color has become more yellow than before.
4. The front and rear ends of caudal fin turn yellow.
Male fish will obviously attack other male fish.
Chocolate doll is a kind of ornamental puffer fish, and chocolate doll is the smallest among ornamental puffer fish. Among the many species of ornamental fish, the ornamental fish of dolphin family is a special species, and many people know nothing about them. Usually, when people find them in aquarium shops, it is hard to resist their temptation: sweet and lovely little faces, smart and trembling fins and round bodies. But after a few weeks, the problem came. Those cute little guys are not as lively as before. They either hide or crawl under the water, and the tiny fins on their obese bodies no longer flap. These fins are listless and drooping, and the bright body color of the past is gradually fading. The scene of wolfing down in the past will never be seen again. Sad blue eyes are staring at the master, but the master is often helpless. In fact, because chocolate dolls have some special requirements, the owner should study the needs of these little things and establish a suitable environment for them to meet their requirements.
To make the little guy live a healthy and happy life in your home, you need to follow the following principles:
Principle 1: Minimize their stress. Stress will destroy their immune system and make them easy to get sick. Establishing a comfortable family and living environment for them is a good way to relieve stress. You might as well arrange something for them to hide in the jar. Aquatic plants with broad leaves, caves and heavy trees are a good choice. These little guys will be more active in the evening and at night. During the day, they usually like to hide and rest. In addition, constant water temperature and PH value are very important for them, because they are actually very sensitive. Besides, they like the house with bottom sand. Of course, filtration and water flow are also necessary, but the water flow is slow, maybe they like quiet. It is also important to choose the right partner for them. We can choose suitable playmates for them by considering the factors such as body shape and habits, and of course there may be unexpected situations. For example, little guys often do them a little harm or simply eat them as snacks. If his playmate is fierce, then the little guy may bear it for a while, and if he can't bear it, he will fight with his opponent, who is either dead or seriously injured. After all, the little guy is not easy to mess with. There is something called tetrodotoxin in his body.
Principle 2: Give the kids the right food. The little ones are carnivorous. They don't eat plants, and rarely eat all kinds of artificial feed. The above food can't provide the nutrition that the little guy needs to grow up. Usually, frozen or fresh blood worms, earthworms, shrimps, shellfish, crabs, squid and snails are all their favorite foods. Be careful not to overfeed. If overfeeding may lead to constipation, they often pray for food, even if they are full. Because they love to eat so much, if their bellies get very big, it means they eat too much. You can feed them 1-2 times a day. Usually, their stomachs will collapse a few hours after feeding. If their stomachs are always bulging, then your little guy may be constipated.
Principle 3: always check the physical condition of the little guy. As a daily habit, carefully check the whole body of the little guy every day to see if there is any possibility of external diseases, bites and injuries caused by parasites, bacteria and fungi. By the way, observe their activities and see if their actions are abnormal. One of the advantages of this routine inspection is that the little guys will know you soon. When you come to the tank, they will hover and swim up and down in front of you. Pay attention to several bad signs:
1. He has a bad appetite. Actually, the little guy is very greedy. If he is found to have a bad appetite or picky eaters, there must be something wrong.
2. Press the line. If you find dark gray lines between the back and abdomen on the side of the little guy, these lines can extend from the mouth to the tail, which is also a bad sign.
3. For the type of white belly, if the little guy's belly turns black and the color deepens, you should also pay attention.
4. Under normal circumstances, the color of the little guy's back will change with the time of the day and other factors, but if the color of his back gradually darkens, it will not become a normal body color for a long time, which is also one of the danger signals.
If problems are found, carefully check the living environment of the little guy (salt temperature filtering PH, ammonia and nitrite concentration). If there is no problem, make sure that there are no other terrorists (some big fish) in Tanqueray, and Tanqueray has enough hiding places for him to rest. If all the above conditions are normal, it is necessary to carefully check his body for physical damage.
Chocolate dolls are the smallest puffer fish in the world.
