Choosing a healthy betta fish requires attention to multiple aspects, including appearance, condition, appetite, and group situation. Here are some specific selection tips:
Appearance inspection:
Observe the body shape of the betta fish and choose Thai betta fish with a body length between 5 and 8 centimeters.
Check whether the fins are intact and avoid choosing betta fish with missing fins or physical deformities.
Pay attention to the color of the betta fish. Choose betta fish with bright and rich colors and avoid those with lighter body colors, as this may indicate that they are in a sub-healthy state.
The wide fins should be very graceful when swimming, which is a good indicator.
Condition observation:
Observe the behavior of the betta fish. Choose an active betta fish and avoid those hiding in corners or sinking to the bottom of the fish tank, as these betta fish may be unhealthy.
Pay attention to whether the betta fish shows symptoms such as clamped tail, burned tail, rotten fin pinholes, white spots, saprolegniasis, white head and white mouth, and ascites. These are all signs of unhealthiness.
Appetite test:
You can observe the appetite of the betta fish by throwing some food into the fish tank. Betta fish that are actively competing for food are usually more energetic.
Group observation:
Check if there are sick or dead betta fish in the fish tank. Because the fish in the same fish tank are likely to be infected already, the chance of getting sick after buying them back will increase.
In conclusion, choosing a healthy betta fish requires comprehensive consideration of factors such as the appearance, condition, appetite, and group situation of the betta fish to ensure that the selected betta fish is both healthy and has good ornamental value.
