Hi, My pair of A.cruzi has spawned twice in the last 2.5 weeks, but both times there were no fry. Female is guarding the eggs, but on the third day they all turn whitish and dead. Female looks kind of embarassed for the second time in a row. What can I do to prevent it from happening again? Lots of plants, pH 5.7, soft (dont know how soft, 80% RO), 81 F, lots of hiding places. Thank you Lilia
