The majority of the spawns have come from the main breeder. This is the tank where I have done most of my experimenting on. I would say on average, the typical parms for this tank would be 74temp, 7.2-7.4 pH, GH/KH ~ 4 and TDS around 120.
Other notables on this tank are that I do use DIY CO2 and still use the PMDD version of fert dosing.
My most surprising spawn came in the tank where I use Safe-T-Sorb as a substrate. Water is very acidic at ~ 5.5. This particular tank gets a higher concentration of CO2 and EI fert dosing. This tank also sits in the upper 70s for temp.
One note that I have observed though is crowding. When the tank is too populus with shrimp and/or Otos, the spawning decreased greatly. I attribute this to too much activity in the tank.
Is their a particular set of parameters that you are finding greater success with? Any luck with the zebras? Sorry if these have been answered I havent followed the thread to closely.
Nothing yet to report on the Zebra's. I have a couple of ladies getting ready to join the project so hopefully, with the better ratio, I can get something started there.
Macros are still just not with the program. These boys seem to be completely clueless when the lady is ready. I'm actually getting ready to replace them.
