Hi all,
Apistogramma breeders tend to keep Pencil fish or Hatchets as "dithers", this is because of the problems with most Tetras picking of the fry.
I've got Black Neon and Pristellas (X-ray) tetras in with mine at present. The Black Neons are good dithers, and stay away from the cichlids well up in the water column, but the Pristellas (2 rescue fish) are great fry hunters.
cheers Darrel
