Apistogramma cacatuoides and Coral Red Pencilfish

Since my killifish still haven't hatched, I've been looking at my options for breeding set-ups. If I go with show guppies it will cost me at least $75. (Assuming I didn't need a second strain to maintain the first, like in the case of needing gold reds in order to maintain half black reds.) Thus I figure anything in between is fair game. For around the $75 I could pick up a small school of Coral Red Pencilfish and for even less I could pick up a pair of Apistogramma cacatuoides. I was looking at breeding my own fish for a Peruvian Amazon biotope, but the fish are from different areas. (Coral Red Pencilfish are from the Rio Nanay which is black water, but I think the Apisto's have a wider distribution in white water...) If I want to be accurate I can pick up fish from the same local as whichever of the two I end out choosing. I'll update with more on the one I end out choosing.
