The male will pursue the female relentlessly. You will need to provide shelter for her.
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.
guppie
no because the betta will fight, hurt or maybe even kill the guppie
Guppie, Clownfish, Cod
No, clown fish are marine fish and tetra and guppies are freshwater fish.
No, he will get killed by the guppy.
the big guppie I think
The best family fish is either a blue geromie, a betta, or a guppie, or a gold fish. None of these fish need a filter.
A guppie is a tropical fish and should be kept in an aquarium with other tropical fish, a goldfish is kept in a bowl or tank in cold water - the 2 cannot be kept together because of the different in the temperature of the water
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 fishes need filtering every week or 2 weeks
They can have up to 30-50 fish, but mine only had one? Can anyone explain that?
