Hi, I'm amazed that Gary got his Pandurini to spawn at pH 6.5. Mine did nothing until lowered to about 5.5, just like my A.nijsseni. I agree with Mike that at least 3 weeks before raising the pH in the fry tank, and that it should be done very slowly. I wrote an article on them that will be published in the Northwest Aquaria, the newsletter of the Greater Seattle Aquarium Society, don't know which month yet.
