My 6-month-old male betta's fins aren't growing. Should I worry?

Question

I bought a "male betta" and he is about 6 months old now and he isn't growing his fins out. Should I be concerned? Am I doing something wrong? Pet's info: Fish | Unknown - Fish | Male | 5 months and 8 days old

Make sure you have a male instead of a female Betta. Determining sex can be tricky in young Bettas until about two months of age. You can post a picture in Jake's profile or attach an image to a new question. If he is indeed a male with short fins, check for signs of infection such as fin rots. Signs include ragged fins, clamped find or lethargy. Water quality plays a role in overall health, so make sure the tank or bowl had adequate filtration, chemistry and oxygenation. If necessary, there are medications that can be purchased to treat bacterial or fungal infections that contribute to fin rot. Check the aquarium section in your local Petco for broad spectrum medications. Follow label directions carefully.
