Background of Betta fish
The Betta fish or Siamese fighting fish was described by Regan in 1910. It is a perch like ray finned fish which belongs to the family Osphronemidae under order Perciformes of class Actinoperygii. The genus name ‘Betta’ was taken from the Javanese name ‘Wuder Bettah’”. Other common names of betta include Split-Tailed Betta and Libby Betta. In Thailand, it is called “pla-kat” which means Fighting Fish. This species is now listed on the IUCN Red Data Book as Vulnerable species (VU).
Housing Betta Fish
The betta fish is probably the second most popular fish after Goldfish. It is a favorite due to its beauty, long fins and is relatively easy to care for. A betta requires at least 5 gallon tank for a single fish but 10 gallons or larger aquarium is recommended. It is a peaceful fish which can be kept with other peaceful species of fish such as Tiger Barbs. They become aggressive with other bettas and tropical fish with large fins such as guppies, angelfish and others. They are hardy fish and can adapt to most aquarium conditions and their special ‘labyrinth organ’ enables them to survive in oxygen-depleted waters. This species does best in a well-planted and shady tank with plenty of surface areas. The plants should be floating types such as Salvinia or Riccia species or tropical lilies such as Nymphaea. Driftwood, other plants such as Microsorum or Taxiphyllum species, small clay plant pots, plastic pipes or empty camera film cases can also be included to provide extra shelter.
Feeding Betta splendens
The betta or Siamese fighting fish has upturned mouth and it is primarily carnivorous surface feeder. In the wild condition, it mainly feeds on zooplankton, crustaceans, the larvae of mosquitoes and other water-bound insects. In captive condition, it should be fed commercial betta pellets. It also accepts small live or frozen invertebrates and small fish. The feed should be supplied couple of times a day.
Breeding Siamese fighting fish
Like many gouramis, the Siamese fighting fish is bubble breeder and the male builds bubble nest of various sizes and thicknesses at the surface of the water. They breed in bubble nests and do not require a large tank or special equipment. Ideally the fish should be conditioned prior to breeding by feeding them a diet of live foods. The water should be at a pH of about 7.0 and temperature around 80 0F or slightly above. The female should be provided with a hiding place before spawning. The female lays around 10–40 eggs during each embrace. The male releases milt into the water and fertilization takes place externally. During and after spawning, the male uses his mouth to retrieve sinking eggs and deposit them in the bubble nest.
After spawning, the male guards the nest, taking care of the eggs until the young hatch 24 to 48 hours later. Newly hatched larvae remain in the nest for the next two to three days until their yolk sacs are fully absorbed. Afterwards, the fry leave the nest and the free-swimming stage begins. In this first period of their lives, the fry are totally dependent on their gills and the labyrinth organ to breathe atmospheric oxygen. The male should be removed within two days after the fry hatch to prevent them from eating eggs. The fry should be fed with baby brine shrimp or very fine baby food. The feed should be offered two times daily.
Sexing betta fish
