Bettas can be vulnerable to a variety of illnesses. Knowing how to distinguish specific symptoms is essential so you can take immediate steps to isolate the sick betta and protect the other fish in the tank. Even if you don't have other fish in the tank, using a one-gallon fish bowl for your sick fish will make it easier to administer medications. Just make sure that you use the same tank water from his usual tank to avoid an abrupt change in his immediate environment.

Before familiarizing yourself with common symptoms of various health problems affecting Betta fish, it is important to know how to distinguish between a healthy and sick betta.

Signs that are commonly observed in a sick betta include:

  • Loss of appetite; may eat and spit out his food.
  • Lethargic; may lay at the bottom of the tank and only come up to the surface for air.
  • May dart and rub their body on tank décor and substrate in an effort to scratch themselves.
  • Appears to have a dull color, pale, and may turn gray.
  • Tails or fins may be clumped, closed, stiff, or falling apart.
  • Appearance of red spots, open sores, white cottony patches, lumps or white spots on their body.
  • Eyes may be swollen or protruding, and may appear cloudy.
  • Scales are raised.
  • Belly looks abnormally swollen, big, or too hollow.

Here are some common Betta health problems and their symptoms to help you diagnose and treat the condition.

  • Redness around the infected site, lethargy, loss of appetite, and rubbing their body against tank décor or substrate.
