Bettas, also known as Siamese fighting fish, are known for their beautiful colors and smooth fins. However, if you bought your betta from a pet store, chances are you don't know how old it is. It is difficult to determine exactly how old a betta is, with some common sense and the observation of your fish you can make a good one cute.

To step

Method 1 of 2: Determine age based on characteristics

1. Check out the size of your betta. Normally, adult bettas are about 3 inches in length. Hold a tape measure along the side of the tank to see how long it is. If it is shorter than average, it is probably a juvenile fish.
   • It can be difficult to measure your fish precisely. In most cases it is enough to make an estimate using the tape measure against the aquarium. Be patient, most bettas don't hang around for long.
2. Check your betta's fins. Adult bettas have nice, smooth fins. If your betta has such fins, it is likely that it is an adult fish. If the fins are small, your fish is a baby or adolescent.
   • Older betta's fins usually show signs of damage. They may have small tears or frayed ends.
   • Make sure you know the gender. Females never get the long, smooth fins that males get.
   • Do not confuse normal damage with injuries from illness.
   • Crown Tail Bettas naturally have fins that look "torn".
3. Evolution the color of your betta. In general, young Bettas have vibrant colors and older Bettas have a slightly faded color. The color of the scales of an older betta are slightly fainter and duller.
   • Bettas that are bred as pets come in many different colors. However, wild bettas are usually gray or dull colored and only show some color when fighting.

Method 2 of 2: Identifying the signs of aging

1. Watch for changes in your fish's body. You may notice that your betta is getting paler by the day, or even your fish is getting thinner even with daily feeding. These are signs of aging.
   • As a betta ages, its back may start to arch. An old betta's back is almost always arched, while a young betta's back is straighter. The hunchback is rounded, so don't confuse it with a problem in the spine, which is bent abruptly.
2. Pay attention to the change in energy. Your betta will then parade with less pleasure at first when he is older. After a few years, most bettas lose the will to show their fins.
   • Furthermore, a healthy adult betta will swim around energetically, while old bettas will hide behind plants and decorations and swim more slowly.
   • When you feed your betta, watch him closely to see how quickly he notices his food. Older Bettas may swim more slowly for their food and may miss it a few times before seeing the food.
3. Look forward to staring into your betta's eyes. Older bettas usually have cataracts, a blurry spot in the eye. This is normal in older bettas and will happen regardless of how big the tank is and how clean the water is.
   • If the fishes' eyes are black and hard to see, that is a sign of a healthy adult betta.

Tips

• If you take good care of them, bettas can live between 2 and 6 years.
• Mark the date you bought your betta. This will help you keep track of how old your betta is.
• Never keep two bettas in one tank unless you are an experienced fish keeper.
