I'm working on breeding mosquito fish from the local creek (Rosa, my WC radix LOVES them!!). I have about 30 roughly 2/3 female 1/3 male. I've had successful broods that were quickly eaten by the bigger fish in the tank. Just put in a large "breeding mop" so hopefully the next broods will have more of a chance. I'm a bit lazy, so want to avoid the separation tanks and such. Hopefully want to set up enough hiding places that fry can grow. Any other ideas?
