So far I've tried red rili x blue rili crosses by placing RR and BR in the same tank. I've wound up with red rilis with barely noticeable blue in the middle, blue rilis (no red), red rilis, and the occasional cherry. These have all interbred.
I've separated out 5 or so that have at least some blue in the middle, and now have 1 berried. It will be interesting to see the shrimplets and see how I proceed from here.
Does anyone else have BBRR or RR yet? Is everyone in the planning stages?
I know some people are setting up tanks.
