When your Betta fish is fasting it means it is not eating, this usually happens after the Betta has bred and it will not eat until all the Betta eggs are hatched.
The wobbly bump under the chin, known as a "double chin," is caused by excess fat accumulation. To reduce it, a combination of regular exercise and a balanced diet can be effective. Engaging in exercises that target the neck and chin area can help strengthen the muscles there and reduce the appearance of a double chin. Additionally, maintaining a healthy eating regimen can aid in overall weight loss. The double chin removal wand is a non-invasive option that may help, but it's advisable to consult with a healthcare professional before using it to ensure it's the right choice for your specific needs.
I believe you mean Betta fish. No, it should be fine. You can treat you Betta fish by giving them bloodworms!
It might meen that your betta fish is about to lay eggs.
Yes they do sometimes they do want to mate with each other so they have sex and then if you see the female having a bump in the belly that means it is pregnant or it's sick and then she will release her babies in a couple of months.
