Betta Fish Diseases: Quickly spot and cure them

Betta is a small colorful perch-like, freshwater fish which is also known as Siamese fighting fish. It is native to Thailand and Cambodia. It is found in small ponds, rivers and other small water places. It grows up to 7 cm in length and can live about 2-4 years in captive condition. They have upturned mouths and they are primarily carnivorous surface feeders.

In the wild condition, their diet consists of zooplankton, crustaceans and the larvae of mosquitoes and other water-bound insects.  It prefers warmer water climate (25-30°C) and it can survive in a low-oxygen level of water. Poor water quality makes this fish more susceptible to diseases. Beta fish health is closely related with habitat environment. In order to keep these fish healthy, habitat water should be checked routinely and cleaned. Intensive care must be provided.

They are attacked by different types of diseases due to less than ideal environmental conditions. The causes of these diseases are fungus, bacteria, Protozoa, Helminthes, Crustaceans, Virus and many environmental factors. Physical symptoms and abnormal behavior indicate that the fish is infected with one or more diseases.
