Here is a detailed guide to betta fish feeding, which combines the most authoritative and up - to - date content from the search results:
Basic Feeding Essentials
Feed Selection and Feeding Frequency
It is recommended to use special slow - sinking pellets such as Tetra Tropical Granules. These pellets are rich in protein and vitamins, which are in line with the feeding habits of betta fish. Feed twice a day, once in the morning and once in the evening. The amount of feed should be such that it can be eaten within 5 - 10 minutes. Feed 5 - 7 pellets for young fish and about 10 pellets for adult fish each time.
Avoid over - feeding, as the remaining feed will pollute the water quality and lead to obesity or abnormal excretion.
Water Quality Management
Keep the water temperature at 24 - 28°C. Chinese betta fish can tolerate low temperatures, but for half - moon betta fish, a water temperature of 20 - 25°C is recommended.
The water should be neutral with a pH value of 6.5 - 7.2, and the dissolved oxygen should be ≥5mg/l. Toxins should be regularly detected (for example, the content of ammonia and nitrite should be 0).
Water change frequency: If there is a filtration system, change 1/3 of the water every 5 - 7 days. If there is no filtration system, change the water every 2 - 3 days. Pay attention to the temperature difference between the old and new water should not be too large.
Advanced Feeding Suggestions
Environmental Configuration
Fish Tank Selection
Choose a square glass tank with a capacity of 2 - 10L. Avoid using a round tank as it may affect the fish's vision. The tank should be covered to prevent the fish from jumping out.
Add Indian almond leaves to adjust the acidity of the water quality, or use Tetra AquaSafe to quickly remove chlorine.
Arrange aquatic plants such as moss and water lilies, and smooth decorations to provide hiding places for the fish and absorb nitrates.
Health Monitoring and Disease Prevention
Common diseases include white spot disease and fin - rot disease. It is necessary to keep the water quality clean and observe the abnormal behavior of the betta fish.
During the breeding period, a separate hatching tank is required. Feed the young fish with brine shrimp larvae in the early stage, and gradually switch to special feed.
Precautions
Single - Tank Feeding
Betta fish are aggressive. If they are mixed with other fish, a large water body is required and they should be paired with gentle fish species. Closely observe for any fighting situations.
Water Flow Control
Betta fish from calm waters do not like strong water flow. Avoid subjecting them to pressure from strong currents.
Daily Interaction
Train the betta fish with a mirror for 15 minutes every day, which helps maintain the fish's body shape.
By following the above methods, the healthy growth of betta fish can be ensured and they will show their best condition.
