Klaus, >that cacatuoides only live 9 months< I had a male Cac that lived over two years. I have found that Apistos are at their peak for breeding while they are young. Probably before they are the fully developed adults you get at the outlets. >Now, could I get away with two females and one >male borellii in the 20 long? Or should I stick with >just a pair? < I would go for the trio. Decorate the tank with plenty small pots. >So, black neons make a good dither< I never use dither fish in my breeding tanks, I may be the exception though.
