Siamese fighting fish

BREEDING: Spawning occurs and eggs are deposited in a bubble nest, typical of anabantids. The nest can be scooped out and the fry raised seperately from their parents. The fry take artemia and dried foods.

Other Comments: The hardest parts are as follows; 1) a ready female, if not she will be damaged and not breed. 2) Maintain a constant temperature (80-82F) 3) remove female when breeding done, male will attack her and may destroy nest. 4) remove male when fry are free swimming, he will eat them. 5) Very important, feed well, RINSE brine shrimp before feeding. Excess salt will stunt growth of fry. Keep tank clean and surface free of film. 6) Keep best females for further breeding stock

Fishkeeping Facts and Tips

Well planted aquariums are not only great looking, they are also very beneficial to the fish. They oxygenate the water, absorb nitrates, reduce algae and provide refuge for fry (and other timid species). Plants like Java fern, hornwort, Amazon sword, Vallisneria (eel grass), Cryptocoryne and Anubias can all do well in a typical home aquarium with the smallest amount of attention
