The males are slightly more colourful than the females, they are also slimmer and they have a tiny hook on their ventral fin. This can best be found when netting the fish. Males seem to stick to the net because their 'hook ' gets caught in the fabric.
Male tetra fish are typically more colorful and have longer fins compared to female tetra fish. Additionally, male tetras may be smaller in size and have a more slender body shape than females. These physical differences can help distinguish between male and female tetra fish.
All I know is that tetra means four.
Those females probably have something that the males want...
it is slightly wider, and has a more curved blue stripe
Male tetra fish are typically more colorful and have longer fins compared to female tetra fish. Additionally, male tetras may have a slimmer body shape and a more pronounced anal fin. Female tetras tend to have a rounder body shape and may appear less vibrant in color.
yes. a neon tetra can live alone but all fish get lonley so on the safe side you might want to buy another fish. and make sure that the sex is diffrent or the male will try to eat the other male.
The problem will not be the tetras coexisting with the Bettas. It will be the female Betta. She will undoubtedly be killed by the male. He may well spawn her first but afterwards, if she is left in his presence he will kill her. Also if he has ova or fry to look after he will kill the tetras in defence of his young.
Don't know tell me
The distinguishing characteristics of a neon tetra female include a rounder body shape, a more pronounced and larger belly, and a straighter blue stripe compared to the male's curved stripe.
Male and female tetra fish can be distinguished by their physical characteristics. Male tetras are typically more colorful and have longer fins compared to females. Additionally, male tetras may exhibit more aggressive behavior, especially during mating season. Female tetras tend to be larger and have a rounder body shape, as they need more space to carry and release their eggs.
Depending on the fish, it might be aggressive towards your tetras and mollies, which tend to be pretty passive fish. I wouldn't, just to be safe.
One way to tell the sex of your neon tetra is that the males tend to be more slender, and the females tend to be a bit more round. Additionally, the line that runs along the body of a male tetra will be straight, while on the female, it will bend a bit.
