Well known for their fighting habits, the male betta siamese have been bred to have magnificent finnage in many spectacular colour varieties. Blue, red and ocean green are the most popular. Females are not as colourful as males, and have relatively small fins.
Originating in warm water, they should always be kept above 18ºC. (The ideal and recommended temperature is 25ºC) . In colder states such as Vic and Tas, they will require a heater during winter months.
These fish are not difficult to breed at home. Females lay eggs which are scooped up by the male and cared for in a floating bubble nest.
