Do Goldfish Lay Eggs Or Live Birth?
Lay eggs
Also sea horses give birth
Yes they do!
Shacks also give live births
Guppies also give live birth. And I'm not entirely sure, but I think platys and mollies do as well.
It's a commen fact that all fish exsept dolfins and whales lay eggs
Goldfish lay eggs so do other fish,its only large mammals such as dolphins that give birth to live young!
