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.
Betta fish can exhibit unusual sleep behaviors, often resulting in new betta owners assuming that their betta fish has died. In an aquarium, betta fish sleep anywhere in the tank they feel comfortable, including at the bottom on the substrate, floating at the mid-level, or at the surface.
Sinum perspectivum, common name the white baby ear, is a species of predatory sea snail, a marine gastropod mollusk in the family Naticidae, the moon snails. [1]
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 breeding. When the female is interested in mating, she becomes lighter coloured and develops vertical bars.
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.
A few species of molluscs, including octopuses and cone snails, can sting or bite. Some present a serious risk to people handling them. However, deaths from jellyfish stings are ten times as common as those from mollusc bites. [43] Live cone snails can be dangerous to shell collectors, but are useful to neurology researchers. [44]
