I haven't sold any shrimp for a while as I was working to increase my population of CBS and also breed my CRS so that when they bred with your shrimp the offspring would contain some CBS even though they are CRS and even if it bred with another CRS. The % arent set in stone but from what I have found is that when my CBS infused CRS bred with my CRS that had no CBS in their family tree roughly 50% of the time I would get at least one CBS and as many as 5! These also contain SSS+ (crown, flower head) genetics too so again, the % cant be exactly determined but you will get higher grade babies unless your breeding them with dirt. Lastly I have always taken great effort to cull all offspring that do not have thick white markings so you can be comfortable knowing my shrimp are saturated with thick/unbroken/pure white where they should be colored that.
Here's the breakdown.
S+ $6 per shrimp
SS $10 per shrimp
