In my past 20 spawns of Mono, I did some test in different water conditon.
At least Mono spawn in ph5.8-7.4 range.
I was thinking Mela (aka Xingu) need a bit higher PH than most SA water because actual Rio Xingu PH is not so low.
However my mela spawned in ph5.8
Intermedia exists in very low PH and very soft water, upper Orinoco region. It's 5.0-6.0.
But my male Intermedia ejaculated in higher PH range than native water.
It was PH6.4 and 6.8
There are lost of spawn of Orinos in such same condition as well
The sudden change of the pH promotes most SA/CA Cichlid breeding. However, in the case of Cichla, they were temporary.
It will take only 6 hours for male Cichla to develope big humped head when big water change.
It is easy to make the male come into rut temporarily. But female is different...
Probably you will get something from my these words
