জীববিজ্ঞান     শব্দকোষ (উদাহরণ স্বরূপ epibenthic)

Occurs in tannin stained blackwater streams (Ref. 12693). Found in forest covered streams including peat adjacent areas. Take around three months for free swimming fries (Ref. 57235). Young individuals feed on insects at the water surface, adults take fishes (Ref. 12693, 57235) and smaller vertebrates (Ref. 56749). A mouth brooder, young about 6 cm at birth (Ref. 7050, 57235). Valued as an aquarium fish, its flesh commands a moderate price.

Life cycle and mating behavior Maturities | প্রজনন | Spawnings | Egg(s) | Fecundities | শুককীট

From an observation of a breeding pair in a concrete tank, courtship lasts from several weeks to months. During this stage, the breeding pair swims near the water surface usually at night. "The male chases the female around the perimeter of the tank. Sometimes, the pair circle each other nose-to-tail. About one to two weeks before spawning takes place, the fish swim side by side with their bodies touching. Eventually, the female releases a cluster of orange-red eggs. The male fertilises the eggs and then scoops them into its mouth where it incubates them. After hatching which occurs in about a week, the young larvae continue to live in the male's mouth for 7-8 weeks more until the yolk sac is totally absorbed" (Ref. 57886).
