Which fish species can reduce the reproduction of livebearers
Livebearing toothcarps become a nuisance in some aquariums because they multiply too much and get the upper hand. Excessive stocking of fish can lead to diseases etc. due to high stress, polluted water and other factors, even if the overstocking is caused by young fish that were born in the aquarium.
People then often look for fish that eat at least a large part of the juvenile fish, but which do not bother the adult fish.
In principle, fish should not only be kept so that they fulfill a specific function. Fish should be kept primarily for interest and pleasure. Of course, you always have to make sure that the aquarium size, water values, etc. match all the species you keep.
If the conditions mentioned are met, the following species can be suitable for limiting plagues of juvenile fish:
Of course, no guarantee can be given that there will be no more offspring with such species. As a rule, however, the amount of young fish is reduced to a tolerable level.
