How do freshwater fish mate?

Answer by  tuppyqueen (311)

Freshwater fish mate like this. The female freshwater fish lays her eggs on the bottom of the tank and then the male fishwater fish comes along and puts his sperm on top of the eggs and that is how the freshwater fish mates. At least that is what we seen on TV

Freshwater fish mate by having the female lay eggs in a nesting area, usually made up of grass and various objects. During spawning, the male fish introduce sperm into the nests that will try to fertilize the eggs. Multiple male fish can fertilize the same clutch of female eggs, leading to multiple "fathers" of the clutch of eggs.

In most species of fresh water fish, the female lays a clutch (group) of eggs on the rocks or in a small niche among plants. The male then sprays his sperm on the eggs. Some species have the male carry the eggs in his mouth, but the vast majority have the female or both parents guarding the eggs.
