Darker coloration, increased aggression associated with a specific object like a smooth rock, cleaning off rocks or smooth surfaces, collecting driftwood fragments and loose leaves. Their vents don't swell much until right before the spawn. They will flare and tail-whip at one another, but that is also common between same sex, so might not be a good indicator. Males sometimes nudge the side/vent area of females with their snout. In larger groups, increased aggression/territorial behavior between females is a good indicator that one or more is ready to breed. Their brood care is really interesting and entertaining, good luck!

Hope that helps,

I'm not sure. What is your pH, gH, kH, TDS, temperature of your water?

i don't know my PH,gH,Kh,TDS but my temp is 77F.
 
With Satanoperca a good, simple rule of thumb is soft and warm. Since you do not test for kH, gH or TDS, I'd pay more attention to the temperature. What other fish are in the tank? If higher temperatures wouldn't compromise their tankmates, 82*+ would be preferred. Mine start courting around 82*, courting heavily at 84* and will breed between 86-88*. In my experience, they don't like being lower than 82*

Goodluck,
Ed
