When goldfish are large enough, they are called carp. Tilapia is not a goldfish or a carp, although the species does have some similarity.
Well..... my tilapia are getting bigger (some 6inches) and my 10 cent walmart goldfish are slowly vanishing... my guess is because they are omnivores that its possible and more than likely.
goldfish do not live on land
Depends on the species of tilapia some can actually do quite well in water reaching the same salinity as sea water. Nile tilapia is the least saline tolerant; 15ppt Blue tilapia = 20 ppt Mozambique and Red tilapia grow well at 33 ppt (~ full strength)
The lifespan of tilapia is about 10 to 20 years in captivity. So in the wild, it is probably a little less than that.
Your goldfish will not live "longer" no matter how many or how few you have.
For househeld goldfish, they generally live 6-8 years
No, goldfish are freshwater fish.
yes
depends, can a ten gallon tank live in a goldfish
A goldfish is a freshwater fish, and as such does not live in the sea.
Goldfish are egg layers
