The main feature of this fish is the navy-blue triangular markings on the body side, and the light pink or olive-green light on the whole body scales. Since the back half of the body has a blue right-angled triangle that glows blue (the male's black triangle markings are larger than the female), the whole fish looks very pretty, so it is named "blue triangle fish."
Blue triangle fish is one of the most eye-catching species of tropical fish. Originated in Malaysia Peninsula, Singapore, Thailand and Indonesia Sumatra and other places. The wild blue tang fish live in the estuary area where salt water meets, and Xi group is active in quiet water or slow flowing waters. The fish is said to have been bred by European and American countries since the beginning of the 20th century and has been favored by many breeders. The fish is small and luxurious. It is also known as the "Queen of the Tropical Fishes" and Neon tetra (Neon tetra).
Second, the morphological characteristics Blue Triangle fish body length in 3 ~ 5cm, fish body's horizontal axis is wider, mouth crack slightly upward. Eyes are large and the iris is shiny red. Scaling, thin and large. Caudal fins forked. The back is red-brown, covered with silver on the front of the body. The dorsal fins, anal fins, and caudal fins are light red with white trim; the pectoral and pelvic fins are colorless and transparent. Some individual fins are also mixed with rose red and blue, which are in harmony with body color.
This fish has the distinction of big blue triangle fish and small blue triangle fish. The former has higher ornamental value. The large blue triangle fishes are larger in size and the triangles have darker spots; the small blue triangle fishes are slightly smaller, and the dark spots have poor clarity.
Third, feeding method Blue triangle fish like soft water, so the fish tank should use full glass, do not use the old type of ordinary fish tank, the water should be appropriate to add some humus. The water temperature is preferably controlled at 24 to 28°C. At the beginning of breeding, 1/2 cold water or 1/3 distilled water can be injected into the fish tank to gradually adapt the fish. In the breeding process, more filters should be opened, less water change; generally every 3 ~ 4d change once, each time the amount of water to replace the original water is not more than 1/10 is appropriate.
The fish is not demanding on food, and live bait and dry feed can feed, especially small live baits. To keep the water clear, do not use oversized and easily precipitated feed. During the feeding process, excessive feed tends to make the water turbid. Generally, it is sufficient to feed the feed once a day. This will help stabilize the water quality and help the future breeding.
Blue-triangular fish are very susceptible to white spot disease. To prevent pathogens from being carried into the fish tank during daily feeding, and to pay attention to changes in water temperature in the fish tank, it is best to control the water temperature at 24 to 28 °C to prevent ≥ 3 °C in a short time. The temperature difference. In seasons with higher temperatures, fish tanks should not be placed close to the window to prevent fish diseases due to large temperature difference between day and night.
The fish is gentle in nature, will not attack other fish, and can get along well with other kinds of fish, but it cannot be mixed with large or ferocious fish. Otherwise, it will not be able to freely and normally feed due to being bullied. The body is wasted and the color is bleak, losing its ornamental value.
Aquatic plants embedded in the aquarium can increase ornamental quality, but in order to reproduce, the pH of the water must be reduced. Therefore, we must choose those plants that can survive under the acid conditions.
Four, male and female identification In the non-reproductive season, male and female blue-triangular fish is more difficult to distinguish before the start of reproduction, male body color becomes brighter than usual, body size appears slender, "black triangle" part is larger than the female; female The body of the fish is thick, the abdomen is relatively swollen and its body color is lighter.
Fifth, breeding methods
1. The choice of broodstock is to choose a full-length fish with a length of 4 cm or more and about 8 months of age as a broodstock. Prior to spawning, a pair of male and female brooders are kept in an aquarium for a period of time (appropriately for two weeks or so), enough leeches and red worms are fed, and the water quality is kept fresh.
2. The breeding aquarium is prepared to select an aquarium with a size of about 60cm30cm35cm, and the bottom is washed with washed gravel. Planting water plants in the breeding box at a fractional level, using broad-leaved plants (such as crowngrass, sandalwood, and barnyardgrass) is good, as well as stonegrass or some hair grass at the bottom of the tank. The plants must be planted densely, as the females lay their eggs under the leaves of the plants under the male chase. In the aquarium, 1/2 distilled water or cold boiled water is injected into the aquarium and the other 1/2 uses old water that has been placed for more than 5 days. The pH of the propagation water should be adjusted to 5.5 to 6.5, the water hardness to 1, and the water temperature to 26°C.
3. Spawning A pair of broodstock that have been raised for a period of time will be placed in the breeding aquarium. Soon after, the males will be found following the females. The female swims from time to time on the back of the females. This is a sign of the upcoming spawning. If there is no such phenomenon after 2 to 3 days, then a pair of broodstock should be replaced.
It is best to place the male fish into the breeding aquarium before allowing it to be used in the box before putting in females, which can increase egg production and hatchability.
After the broodstock is placed in the breeding aquarium, the males first swim around the females to show courtship. When the females are fired, both males and females start looking for attachments (waterweed blades) on which they are about to lay eggs and find suitable spawns. After the location, they rotate together in the vicinity, and the females will pick and go on the selected grass blades. During reproduction, the females first produce eggs on the back of broadleaf weeds. The males are then immediately ejaculated and fertilized. Females spawn about 4 to 5 capsules at a time. Such mating spawning activities are repeated several times until the mature eggs are exhausted. Spawning time is usually around 10am. One female at the beginning of the first production lays only 20 to 50 eggs, and the next one can produce 80 to 100 eggs, and more than 200 grains. The egg is small and transparent, with stickiness, attached to the back of the water grass leaves. After spawning, broodstock should be removed to prevent them from swallowing eggs.
In order to increase the spawning rate and hatching rate, the breeding aquarium should be clean and the plants should be fully washed. Before spawning, it is best to place 3 to 5 mL of acridine yellow solution in the breeding aquarium to reduce the chance of bacterial infection. In addition, the spawning environment should be quiet and the light should be slightly darker, otherwise it will interfere with spawning.
4. Fertilized eggs were hatched from 24 to 36 hours and the larvae broke out. In other words, if the eggs laid are transparent, the larvae can be hatched on the 2nd day. After 3 to 4 days of development, larvae can swim freely.
After the yolk sac in the abdomen of the larvae was depleted, the washed “drip water†(small zooplankton such as rotifers) was fed. A little later, gradually changed to individual larger zooplankton.
