The bettas exhibit two kinds of spawning behaviour: some build bubble nests, such as B. splendens, while others are mouthbrooders, such as B. picta. 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.
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 ...
Dart frogs housed in a heavily planted bioactive display terrarium. A bioactive terrarium (or vivarium) is a terrarium for housing one or more terrestrial animal species that includes live plants and populations of small invertebrates and microorganisms to consume and break down the waste products of the primary species.
Betta smaragdina 'Guitar' is a naturally occurring variety or even subspecies that lives only in the Bueng Khong Long, Bueng Kan province in northeast Thailand (Isan). What makes them differ from the normal B. smaragdina are their guitar like markings on the dorsal and caudal fin.
Bettas are known as anabantids because they have a special lung-like labyrinthine organ in its head which enables them to obtain oxygen direct from the air. For this reason, they can live in water with very little dissolved oxygen, and can survive out of water for a short time as long as they remain damp. They are also efficient jumpers. [4]
Mouthbrooders, spotted bettas spawn en masse when triggered by water changes; this is likely to be an adaptation to reduce the chances, by saturating the environment with young, of individual fry falling prey to predators. This betta spawns readily and prolifically in captivity, producing easily raised fry.
How often to feed betta fish. Betta fish should be fed at least twice a day, Aquatic Veterinary Services reports.Their meals should also be spaced out by six to eight hours.. Bettas are natural ...
A temperature-controlled terrarium with plants inside. A terrarium (pl. terraria or terrariums) is a glass container containing soil and plants in an environment different from the surroundings. It is usually a sealable container that can be opened for maintenance or to access the plants inside; however, terraria can also be open to the atmosphere.
