Hello John I have had success with MacMasteri spawning very easily in my tap water with a pH of 6.8 and 60 ppm hardness. I curently keep the double red strain and have a tank with about 50+ fry that are around 3 to 4 weeks old swimming and doing well. I spawned these guys in near neutral pH water. I've also spawned them several years ago in similar water conditions. I personally found Macmasteri to be one of the easier Apistos to keep and spawn. Then again maybe I'm just lucky in that aspect. What easy for one is sometimes difficult for others. I can't for the life of me get my big beutiful pair of Atahualpa to spawn where as I've heard others say they have no problems with them.
