As is typical of most bettas and gouramis, spawning involves a male building a bubble nest (a floating mat of saliva-coated air bubbles, often incorporating plant matter) and attracting a female to it. If the female accepts the male's advances, the fish will 'embrace' in open water, releasing both eggs and sperm into the water.
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.
Bettas are anabantoids, which means they can breathe atmospheric air using a unique organ called the labyrinth. This accounts for their ability to thrive in low-oxygen water conditions that would kill most other fish, such as rice paddies , slow-moving streams , drainage ditches, and large puddles .
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]
Male individuals of Betta smaragdina will build a bubble nest before breeding. The temperature at which breeding typically occurs is 25.6 to 26.7 °C (78.1 to 80.1 °F). Males and females can live together and the male and female should already live together for breedi
Tropical fish is a term commonly used to refer to fish that are kept in heated aquariums. Freshwater tropical fish are more commonly kept than saltwater tropical fish due to the common availability of fresh water sources, such as tap water, whereas salt water is not commonly available and has to be recreated by using fresh water with sea salt additions.
Many color and tail pattern varieties exist. They generally need a ratio of 1 male to 2 females or more. All guppies and mollies are hardy fish that tolerate lower oxygen levels and temperatures than most aquarium fish, give birth to live young, and readily breed in home tanks. [58] can live in full sea water [59] 66 °F - 84 °F (19 °C - 29 °C)
Kelp forests can provide shelter and food for shallow water fish. Other nearshore or shallow water fish live near the shore in depths of less than 10 metres. They occupy the areas over sandy or rocky bottoms, and can be associated with seagrass meadows and kelp forests. They can be divided into demersal fish and pelagic fish.
