Yup, better luck next time...and I'll be more prepared next time too. Gotta get some Methyl Blue just in case I see eggs in the future.
But in terms of getting them to spawn, what everyone said in this forum is correct. I did weekly 20% water changes and the water that I put into the tank is 2 degrees cooler than the tank temperature. I syphoned the water back into the tank from a bucket thereby mimicked a rainfall and the cories just went at it
EDIT: Oh, I also started feeding them bloodworms and that may have also helped getting them to spawn due to the higher protein intake.
