Why is it that we recommend a ratio of 2 males to 1 female in the majority of the fish we keep?
We can even see this imbalance in wild populations as well as our aquarium fish at home. Why is it that we recommend a ratio of 2 males to 1 female in the majority of the fish we keep? Keeping this imbalance of sexes encourages the natural behavior of a large proportion of fish that we keep in our hobby. If there were exactly 1 male for every 1 female of a species in a given habitat in nature, there would be no competition.
