Pat your observations certainly don't fly against what others have noted on wilds spawning in captivity. It does however raise a question. If its true that wild discus in captivity are more likely to spawn at a time that corresponds to the rainy season in the Amazon than that means its a hardwired instinct as the flooding of the forrests obviously does not occur in tanks. I would think something like that would be hard to breed out of them in domestics. But we know domestics breed pretty much years round. If thats the case then that would be one of the first traits that we know of that have been lost from the wild to domestic breeding routines. For me thats very interesting because I routinely cross wilds to domestics so going forward I will have to pay closer attention to when my crosses breed most.
Obviously none of this is hard science but interesting all the same.
If all goes well I have a group of wild greens coming to me very soon. Should be an interesting next few months.
