hey there, to tell you the truth is doesnt really matter all that much. Just make sure that u get 1 female to 2 male guppies or else the males are really going to stress out the female by chasing her and could possibly kill her by stress. You might want to watch out for tetras, its quite a possibility that u might get one or two nippy tetras that's might have a go at the guppies tail. But normally they are ok together. catch!
Guppies and Goldfish should never ever ever be together.... EVER.
They should never be in the same tank because Guppies are tropical fish and like to be kept over 70F and Goldfish are coldwater fish and like to be kept below 70F. So Goldfish should not bite guppies because they should never be in the same tank together...
You do not say if the guppies are common guppies or fancy, also how many male and female guppies you have, yes as far as the snails and guppies go, one point to remember is the tank water should be above 72 degrees and some live floating plants for the guppies too hide in.
If the goldfish is big enough and the guppies small enough, yes the guppies could well be eaten by the goldfish. Also, guppies should never be with guppies are guppies are tropical fish and goldfish are coldwater fish.
I'm not sure but some people say you should or the baby guppies will breed.
open your mouth and talk about guppies. oh and you should do some research on google.
How big are the two tanks, and how many guppies do you have
No Clown fish are good with guppies although it is possible to keep clown loaches (Botia macrocantha) and Guppies together for a while. Don't forget though that Botias are shoaling fish so they should be kept in groups. They also grow to around 14inches long so need a large tank.
You should wait until the baby guppies seem to be big enough.
Aquatic turtles naturally eat fish in the wild and they will do the same in captivity. For the safety of your guppies your should keep the two species separated.
Maybe you should do your own research.
They can live with goldfish. They can live with small catfish. The ones like you get at walmart. They also get along good with other guppys. You can put as many together as you want, and they will be fine. Hope this helps.
