Although I have heard of cacutoides breeding at pH 7.8 and med-hard water. My Apisto tanks are all at 5.0-5.8 and almost no hardness which seems to work for most Apistos except borelli. With cacatoides one requirement is sufficient suitable breeding sites for the females - very low caves with a wide shallow entrance, perhaps this is the trigger they need.
