Cherry fish (Barbus titteya Beraniyagala) belongs to the class Cyprinidae, Barbinae. Because of its rose color as the base color, it is called the red rosefish; because of the estrous fish, the male has a marital color, bright like the cherry flowers that have just opened, and cherry cherries, cherries and other names. English names include Cherry barb and Crimson carplet.
Cherry fish is native to Sri Lanka and is a small tropical fish. The fish is small and exquisite, colorful, except for the serrated gold line between the sidelines, the body is cherry red. If the aquatic plants in the aquarium are properly decorated with appropriate lighting, the colors on the fish body are particularly attractive; if the breeding environment is poor, the body color is relatively flat.
First, the morphological characteristics of fish petite, body shape is long oval, a total length of about 5cm. The head is small, the tip of the snout, the lower jaw of the mouth, and the lower jaw has 1 pair of whiskers. Body side scales are large and thick, showing a half-moon shape. Sideline is incomplete. The dorsal fin spines have fine teeth behind their spines. The starting point of the dorsal fin to the snout end is less than the distance from the tail base. Pectoral fins do not reach the pelvic fins, pelvic fins do not reach the anal fin, anal fins are short, and caudal fins are forked.
The body color tone is dark cherry red, but sometimes it turns pale brown with health and environmental factors, sometimes turning it into peach green. On both sides of the body, there is a wide stripe of gold and black irregularities. From the kiss ends up through the eyes to the caudal peduncle, there is a serrated golden stripe from the eyelids, interlocking with the black stripes below. Together until the tail handle. The backs above these two vertical lines are darker in color and red-brown. All fins are red. The iris of the eyelid is silver-white and can give off pearl-like splendor.
The male and female characteristics of the cherry fish are obvious, and the body color of the male fish is relatively bright, especially during the breeding period. When the male estrus, its body color is cherry red, very eye-catching, body vertical strips often fade; females always maintain the original color, body brown vertical bands have remained unchanged, more fat body shape, abdominal swelling.
Second, feeding methods In the natural environment, cherry fish inhabit the shade of a small river or stream; breeding in the aquarium afraid of surprise, when the sound is too large to hide in timidity. Therefore, it is best to plant some aquatic plants in the aquarium to allow it to hide and avoid surprises.
In healthy and normal conditions, the cherry fish is lively and loves chasing and jumping and sometimes jumps out of the water. In order to prevent fish from jumping out of the box, the aquarium should have enough space to leave room for the fish to swim; and the box should be covered.
Males have a habit of dominating but they do not fight. When the two males and the females are together, the males will each rotate, enhancing their own marriage colors, competing in contentment, showing off their gorgeous colors to win the favor of females.
Cherry fish swim agile, fear of light, often in the lower layers of aquatic activities, so the light of the aquarium should maintain low light, and plant some aquatic plants to weaken the light. They are more adaptable to the environment, can tolerate lower dissolved oxygen, grow well in water temperatures of 22-30°C, and have an optimum water temperature of 23-25°C.
The diet mainly feeds on small zooplankton. Its mouth is as small as cherries and is not good at contending for food. Therefore, small baits should be taken when bait is fed. Especially at the juvenile stage, it is advisable to feed artificially-cultivated special bait “dripwater†(containing fine floats of higher density). Creatures, including sand insects, paramecium, etc., take longer to feed each time.
Third, propagation methods Cherry fish are oviparous fish, due to small size, spawning volume is also small, and the survival rate of hatchling juveniles is low, especially in the first week often due to water temperature, food shortages and other halfway to the end.
1. The choice of broodstock is more than 4cm in length, good shape, active and healthy swimming, full abdomen of female fish, and plump body color of male fish can be used as broodstock.
2. Prepare the breeding aquarium before breeding. Beforehand, the aquarium must be washed cleanly, and some soft and small aquatic plants such as foxtail grass, gold grass or duckweed should be planted so that the produced eggs adhere to the leaves and roots of the aquatic plants. The male-female pairing needs to have a process of adapting to each other. Even if the cherry fish growing up in the same aquarium are paired in the same breeding aquarium, mutual biting will occur. You can place a glass partition in the breeding aquarium, separate males and females until they know each other, then remove the partitions and allow the brooders to mate.
The size of the breeding aquarium is 602020cm, the water hardness is 7-9 degrees, the pH is 6.6-6.8, the water temperature is kept at 25-27°C, and the aquarium is placed in a dark place.
3. After all the eggs are laid out, the carefully selected broodstock will be placed in the breeding tank in the early evening. The estrous brooding fish will appear more red than the usual marriage color, excited and active, chasing playful, often splashes of water, and even jump out of the water. The breeding habits of cherry fish are the same as those of other genus fish. Usually after a period of chase in a dim environment, the broodstock begin to line up and spawn together to spawn. The proportion of fertilized eggs is slightly greater than that of water, and it adheres to aquatic plants when sinking.
Since the broodstock have the habit of swallowing eggs after spawning, they should pay close attention as soon as they find out that they have begun to mate. After each copulation, feed a small amount of live bait as soon as possible to induce the broodstock to reduce the fish eggs being swallowed. When spawning and rowing are completely stopped, broodstock should be removed in time. The female lays about 50 to 200 eggs each time, and the number of hatched larvae is smaller. In the spawning period, the broodstock spawn time is about 10 days.
4. At room temperature, the fertilized eggs hatched about 24 hours at room temperature, and the head of the larvae was hung from the bottom of the leaves or the roots for about 1 day, and they began to swim and feed for the third day. He began to feed with "drip water" and he was fed a small fish worm 10 days later. Afterwards, you can grow safely and quickly as long as you care and feed carefully.
