Betta fish life span in a bowl
Chinese fighting fish A.K.A Betta fish is freshwater fish originating from Southeast Asia. In the wild, these fish live in warm waters such as rivers, paddy fields, and irrigation channels.
Generally in either the aquarium or in the bowl, Siamese fighting fish can live between three to five years, depending on when you buy it at the age of the pet store. But to live more than five years it needs special care, for example, the best environment and the best food.
To be honest, betta fish is not suitable to be kept in a bowl. Because in a bowl or in a small place where there is no filter, dirt from Siamese fighting fish will accumulate at the bottom of the bowl and cause water becomes dirty and must often be replaced with new water.
Just information, Betta fish need heating. So the use of heaters in a small bowl can make the water too hot and potentially killing fish.
Factors Affecting lifespan
Diet is one important factor for lifespan. Food for Betta fish like Brine shrimp and bloodworms can prolong the life of betta fish lifespan because they contain high protein combine with special pellets for a Betta that aims not quickly bored to the food we give (Brine shrimp and bloodworms).
Betta fish requires a temperature of water ranges from 73 to 84 degrees Fahrenheit. Do not let the water temperature is too cold/hot because it will affect the betta fish. If the water is too cold then the fighting fish will not eat, and vice versa when the water is too hot they will make the fighting fish die overheating.
So basically Betta fish lifespan in a bowl is ranging from three to five years depending on you take care of him. It is just not recommended to put in a bowl, because of space limitations to move and water must often to be cleaned from food scraps or from dirt.
