Breeding apistogrammas

[Dr.B]

Hey guys i'm ordering 2 pairs of apistos some double red agasiziis and some fire reds. i am finding that they are sensative to water, and need a low pH to spawn. I am ordering 1 pair of each. i am breeding 1 pair at a time in a 20 gallon ( while the other pair will be in the 75 gallon south america tank with some bichirs) i am also changing my gravel to sand adding some driftwood and plants. has anyone else had any expiriences breeding apistos. and if so what worked for you. how many fry did you get, how long did it take for them to spawn, were they aggressive when the eggs were laid? ect... any other things/ ideas will help with the plans thanks in advance
