Top Five Threats to Betta Fish Health and Safety

Melanie L. Marten
Betta fish, with their brightly colored tails and fins, are one of the most popular types of freshwater tropical fish. Sold in stores in tiny plastic cups, betta fish are liberated at home by enthusiastic aquarium keepers. These betta fish are relatively hardy, but do require special care. It is important to recognize the top five threats to betta fish health and safety.

Betta Fish Threat - Improper Tank Size

The majority of betta fish are sold in pet stores or aquarists in small plastic cups. This, obviously, is not their natural habitat. In the wild, betta fish live in flooded rice paddies and resultant puddles and ponds. These areas are characterized by still, shallow water, but with plenty of room to swim around. A betta fish needs at least a one gallon tank to live in. If it will have tank mates - other fish or invertebrates - the tank should be larger.

Betta Fish Threat - Lack of Tank Heating

In their natural habitat, betta fish live in water that is between seventy and eighty degrees most of the time. When kept in a home aquarium, an electric heater should be provided to regulate the temperature of the water. Too cold water will result in sluggishness, ill health, and loss of color.

Betta Fish Threat - No Exposure to Air

Betta fish have a unique organ called the labyrinth organ which allows them to breath atmospheric air. In some popular betta fish set ups, such as the lily vase contraption, the betta fish are unable to access the surface of the water. Since betta fish rely on surface air instead of oxygen disolved in the water, a large tank surface area is recommended.

Betta Fish Threat - Improper Diet

There are specially forumulated foods for betta fish. These can be found in most pets and aquarium stores. Feeding a betta fish tropical fish food, or goldfish food, will keep them alive, but not provide optimum nutrition. Betta fish are also fond of live foods such as blood worms.

Betta Fish Threat - Other Fish

The last thread to betta fish health and safety is the inclusion of other fish in the aquarium. First of all, most people know that two male betta fish should never be kept together. Their moniker, Siamese Fighting Fish, is well-earned. Two males will fight each other until one is dead. They are very territorial.

However, it is possible to keep a betta fish in a community tank, depending on its temperment. Betta fish should be kept with other fish of a similar size. Because of their highly developed fins, betta fish are slow swimmers. Be sure to put them with fish that will offer less competition for food. Also, be wary of any fish nipping in the aquarium.
