Survival of the species. More is better because not all get fertilized. Some eggs get eaten by other fish or after hatching some of the fish get eaten. Not all growing fish find enough food to stay alive and some get caught by fishermen or again get eaten by other fish. As long as at least a few males and females make it all the way to have children of their own then the species survives.
get the eggs out and put them in a separate tank because the fish will eat the eggs.
depends on the fish.
Put the eggs or female fish in a different tank it will be better for the both of them.
take the eggs out and put them in another tank with water!!!!
fish eggs and young fish tend to have many predators that want to eat them so many of them don't survive. By laying large amounts of eggs, adult fish increases the probabilty that one of those eggs will survive to grow into a full grown fish and reproduce.
500 fish
get fish eggs then cook them then put it on a plate and enjoy
It varies depending on the type of fish. For many, female fish lay eggs. The eggs are fertilized by the male fish outside the body of the female after they are laid. The eggs grow into baby fish.
most of the eggs will not survive ...
Well, If the parrot fish lays eggs you should probably seperate it because it will guard the eggs for a few days and then eat it. Put the eggs in a different tank or something.
None. Fish lay many eggs, only some of which become fish.
a fish called deacon can vertalise the eggs,but watch out the male will atack it when you put him in the tank . It happened to my one, and it died. im checking for more info
