Steph, That ph is fine for Kribs, they are pretty tolerant of a variety of pH's. In one book I even read that kribs can tolerate brackish water. Have seen = them spawn in water up to the high sevens but never experiemented with the = ranges. Now some of the other species of Pelvicachromis require softer water. If I ever come out your way I will bring along some apisto's, I think = they are cool fish and would love to see them widely available all over. = So often I will donate fish to the cause, just to get more people raising = them, spawning them and hopefully keeping them in the hobby. Take Care Kathy
