If the tank is large enough there is no reason why not. The basic rules of fishkeeping are . :- 1 inch of fish needs at least 1 gallon of water. :- Every tank needs a permanently running cycled filter. :- Every tank needs at least 50% of its water changed every week. The fish you have named are both tropical and should be kept in a heated tank at around 75F
it is slightly wider, and has a more curved blue stripe
A female usually has a fan shaped anal fin( anal fin is on the bottom of the fish), and a male's anal fin is pointy, or "rod shaped".
The male will pursue the female relentlessly. You will need to provide shelter for her.
Look for a gonopodium, which is a sharp fin protruding out at the anal fin. The one with it is the male.
Male guppies are colorful and females are not. They are usually white or clear in color.
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.
Those females probably have something that the males want...
Because their population grows and their thing grows ;)
I guess its about as possible as a small monkey trying to mate with a gorilla. On paper, in theory, they can probably do it but in practice the chances are very small that they would succeed and its even less likely that any offspring will eventuate.
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.
sounds like you have a male guppy harrassing a female. Simply go and buy a few more female guppies and that way the male will have more than one female to harass.
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.
