I didn't think mine could either. My pH is 8.0 out of the tap with a gh of 10 kh of 14, so moderately hard at least. I put in several small new pieces of malaysian driftwood, about half a dozen indian almond leaves, and the coconut hut for their spawning place. I conditioned with live foods and they spawned. my baenchi upstairs spawned as well. So far, apistos have been super rewarding for me!
