Does anyone know if rosy or tiger barbs would nip at koi in a pond? I hear the tigers are terrible at nipping fins but the rosy barbs are less likely to if in a large enough group? Currently I have mosquitofish in with my koi and they don't bother the koi. I'm thinking maybe like the mosquitofish, the barbs will be less prone to nipping in a pond?(i've had gambusias kill other fish in aquariums when I didn't know better). My goal is to replace the drab gambusias with small colorful fish that I will take inside before Winter. Any info will be appreciated.
