Giant betta (Betta anabatoides) in the Aquarium

  • The substrate should consist of dark, fine-grained gravel
  • The aquarium water should be soft and slightly acidic
  • The water temperature should be around 26 ° C so that the fish feel comfortable and show their full color splendor

Giant betta (Betta anabatoides) Breeding

Giant bettas do not form their own territory and do not build a foam nest.

NOTE: For a successful breeding in the aquarium the fish need above all absolute rest. Therefore, pairs ready to spawn are placed in a separate spawning and rearing tank.

How do Giant Bettas breed?

  • After a longer foreplay in the form of courtship and apparent spawning acts, the actual mating and spawning release takes place. This process corresponds to that of Betta picta and Betta pugnax.
  • The female of Betta anabatoides collects the eggs individually from the U-shaped curved anal fin of the male and then spits them in front of the male’s mouth.
  • The male Giant betta gradually collects up to 200 eggs in its mouth within 6 hours and more.
  • If you forget and leave the spawning pair in the general species tank, other females ready to spawn “approach” the male mouth-brooding fighting fish in order to spawn with him.
  • The male may then swallow part of his old spawn in order to be able to take in the new spawn from the second female.
  • It can happen that a male carries broods from different females at the same time.
  • Most of the time, the first female will vehemently defend the environment of his male against any other female.
  • The fry hatch after about 3-4 days from the eggs.
  • After a further 8 days the male spits out the fully developed young fish
  • If there are any underdeveloped larvae or even eggs in the deeper zones of the mouth, the male retains them until they can also be released into freedom in fully developed form.
