the fishes need filtering every week or 2 weeks
The male will pursue the female relentlessly. You will need to provide shelter for her.
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.
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.
the big guppie I think
No, he will get killed by the guppy.
A mid-wife
no fish should be pregnant before a year
No it won't hurt any fish but the fish might hurt the snail.
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
