Description

Technical Field

[0001] The invention relates to the technical field of fish fry breeding, in particular to a fish fry breeding box for freshwater breeding. Background Art

[0002] Betta fish is a popular ornamental fish. It is oval in shape, flattened laterally, and has a broad, arc-shaped abdomen. Adult fish are generally 3-10 cm long and weigh 16 grams. Males are usually larger than females. Males are usually brighter in color than females, and this varies with the habitat. Common body colors include red, blue, and green, and the tail fin can be forked or round. Betta fish prefer shallow water areas with dense vegetation and slow currents. They have a unique habit of spitting foam to build nests, and are aggressive fish, especially males often fight with each other.

[0003] Betta fish has always been favored by ornamental fish lovers due to its bright color and unique habits. In the ornamental fish market, betta fish is a very popular species with high economic value. Betta fish has strong adaptability to water temperature and can generally survive between 20-30℃. After the male fish spits bubbles to build a nest, the male fish will use its mouth to send the eggs back to the bubble nest for protection, thereby reproducing.

[0004] Artificial leaves can be used to raise betta fish. Artificial leaves can provide a safe haven for betta fish, giving them a quiet corner to rest or lay eggs. Betta fish like to perch on leaves or similar objects, and artificial leaves can satisfy their habit. Artificial leaves are usually very cleverly designed, realistic in appearance, and can add a natural atmosphere to the fish tank. Exquisite artificial leaves can be the finishing touch in the fish tank, enhancing the ornamental value of the entire fish tank. Artificial leaves will not rot or affect the water quality, saving the breeder the trouble of frequent replacement and care. Choosing artificial leaves can provide a comfortable, beautiful and easy-to-care-for living environment for betta fish.

[0005] The existing artificial leaves are attached to the inner wall of the breeding box through suction cups. When the betta fish spits bubbles to build a nest, if the betta fish spits bubbles but is not discovered in time, the artificial leaves will block the bubbles on the water surface. At this time, adjusting the position of the artificial leaves will cause the bubbles near the artificial leaves to burst, which is not conducive to breeding. Moreover, each time the water is changed, the height of the artificial leaves with suction cups needs to be readjusted due to the change in water level. In addition, the existing breeding box cannot fix the heating rod. When people need to take away fish such as betta fish that require a certain temperature, they have to use a heating pad to maintain the temperature of the breeding box, which will make the temperature unstable during transportation. If the heating rod is directly placed in the breeding box, it will cause the heating rod to shake during transportation and hit the betta fish.

[0006] For this reason, a kind of fish fry breeding box of freshwater culture is designed to solve the above problems. Summary of the invention
