i cant get any of my PFRs to breed at all, idk if they are old enough or what.
I'm assuming you are referring to the shrimp? What does pfr stand for?
If is shrimp, then Im not sure either. To give you some parameters that have not been intended, just happen to be.
Dkh - 1 or 17.5ppm
Ph - ranges from 5.65 to 6.3. During the day it drops the most as the co2 is on, and can raise back to 6.3 by next morning. As the Aquasoil is very low in ph, it encourages lower readings.
Temp - 24 Degrees Celcius
Lights hours - 8
Co2 hours - 8, and in conjunction with lights
I was unsure how hard or easy it was to breed them, it kind of just happened. I have had them from juvenile, and for 6 - 7 weeks before they began showing signs of carrying eggs.
How long have you had them ?
After all that I really hope you were talking about the shrimp lol.
