Weissguy, for feed, I use NutraFin Max complete diet flake food for the fry and HBH African Cichlid "Attack" after they reach 2 inches. Tilapia ARE in fact African Cichlids.
For the Blue Tilapia fry, I get $135, which includes the shipping. Since I have some red/blue crosses, I send about 25-50 extra fry for a total of about 150 fry.
I don't think I'd be interested in other tilapia yet. I don't have the extra aquariums for them and since the Blues can survive the lowest temps, mature the earliest, and are the best suited for ponds, I'll stick with them for now. However, a cross between blues and niles makes for a very fast growing fish. The crossing of tilapias seems to only benefit the original cross. Offspring og the crosses seem to lose any benefits of the original parents.
