Just would like to ask if anyone here has had experience with using small amounts of crushed coral (in its primary role as a pH buffer) in Festae setups, specifically in setups where the intention is to breed them? I have been using crushed coral in my filters in all my tanks since about 2006 as a pH buffer, to keep pH relatively constant and prevent fluctuation, with fish like bichirs and datnoids and all manner of cichlids. But I have never kept festae before (may be getting some F0 specimens next week), and knowing they are from rainforest habitats in Peru and Ecuador I thought I should ask. Essentially, what I'd like to know is, would crushed coral hinder my efforts to breed them? Would it increase hardness to an extent that festae will not spawn?
Thanks in advance for any input.
