I've checked in with my LFS earlier today. They can get 4 different Apistos, one is the one that I really want. They can get Agassizii, Pandurini, Macmasteri, and possibly Cacautoides. I have a 55g. I've never kept cichlids before. Which would be the hardiest of the five? I have a few days to decide, they have to order the fish in.
