Socolofi are really nice fish to have but I don't think it would be a good idea putting them in the tank with the demasoni being that their both the same species. Just my opinion though...GaFishMan1181 said:Start with more like 18-20 demasoni. Not sure how good rusty would look with that mix. Dont get me wrong i have a nice male rusty in my all male and like him but they can easily get lost in the mix (they dont have much pop). If it were my tank i would go albino socolofi for third but its not so...your choice :thumb: .
