Betta fish, also known as “Siamese fighting fish”, are a popular choice for beginner fishkeepers. Bettas are easy to care for and can be kept in small tanks or bowls. However, many people do not realize that bettas sold in pet stores are often very young, and have not yet reached their full adult size.
Bettas sold in pet stores are typically 6-8 weeks old. This is still considered a juvenile, and they have not yet reached their full adult size.
In the wild, bettas can live up to 5 years, but in captivity they typically only live 2-3 years. This is due to poor water quality and diet in many home aquariums.
If you are considering purchasing a betta fish, do some research on proper care first. Make sure you are prepared to provide your betta with a high-quality diet and proper water conditions. An adult betta fish can reach up to 3 inches in length, so be sure you have a tank that is large enough to accommodate them.
With proper care, your betta fish can provide you with years of enjoyment.
