Fry harvesting, getting the brooding fish to open its mouth and release the fry, is important if the fry are to be reared artificially. In the case of endangered species, such as Asian arowana, harvesting may be supervised by an official to certify that the fish farm is a genuine producer of captive-bred fish. [3] [4] [5]
The mouthbrooding species are sometimes called "pseudo bettas", and are sometimes speculated to have evolved from the nest-builders in an adaptation to their fast-moving stream habitats. [ 3 ] A phylogenetic study published in 2004 concluded tentatively that bubble-nesting was the ancestral condition in Betta , and that mouthbrooding has ...
A betta fish's lifespan can be impacted by the care it receives, WebMD reports. Bettas may live longer if their tank is clean, the environment is calm and their diet is healthy.
The Krabi mouth-brooding betta, Betta simplex, is a species of gourami endemic to Krabi Province, Thailand. It inhabits karst springs and wetlands, where it lives amongst vegetation close to the banks. This species can reach a length of 8 cm (3 in). This species can also be found in the aquarium trade and
Most, if not all, fish that construct floating bubble nests live in tropical, oxygen-depleted standing waters. [1] Osphronemidae, containing the bettas and gouramis, are the most commonly recognized family of bubble nest makers, though some members of that family mouthbrood instead. The nests are constructed as a place for fertilized eggs to be ...
A molluscivore is a carnivorous animal that specialises in feeding on molluscs such as gastropods, bivalves, brachiopods and cephalopods.Known molluscivores include numerous predatory (and often cannibalistic) molluscs, (e.g. octopuses, murexes, decollate snails and oyster drills), arthropods such as crabs and firefly larvae, and vertebrates such as fish, birds and mammals.

Although commonly seen in fish bowls and advertised as a "small tank pet" Betta Fish needs are largely misrepresented by chain pet stores, especially in the EU and United States. At minimum a Betta Fish requires a five gallon tank with a filter as well as a heater since they are a tropical fish species and have specific temperature requirements ...
Male and female individuals of Betta imbellis can live together outside of breeding season, as well as getting together for breeding. Males will build a bubble nest before breeding. After mating, the male catches the falling eggs and places them in his bubble nest. In 1–2 days, the eggs hatch and continue to absorb their yolk sack for 2 days.
