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 ...
Bettas may live longer if their tank is clean, the environment is calm and their diet is healthy. A closeup shot of a pink female veiltail Betta Siamese fighting fish with aquatic plants in the ...
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
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.
Neritidae, common name the nerites, is a taxonomic family of small to medium-sized saltwater and freshwater snails which have a gill and a distinctive operculum. [2] The family Neritidae includes marine genera such as Nerita, marine and freshwater genera such as Neritina, and freshwater and brackish water genera such as Theodoxus.
Nerita is a genus of medium-sized to small sea snails with a gill and an operculum, marine gastropod molluscs in the subfamily Neritinae of the family Neritidae, the nerites. [ 1 ] This is the type genus of the family Neritidae.
All of these variants have black papillae interspersed among papillae of their main color. There is controversy over whether or not the different colorations are divergent species. [5] Like most other members of its genus, Jorunna parva's diet consists of toxic sponges in the family Chalinidae. However, they are also known to eat algae ...
Lymnaea stagnalis, better known as the great pond snail, is a species of large air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Lymnaeidae. The great pond snail is a model organism to study parasitology, neurology, embryonal development and genetic regulation.
