Anything is possible really. I have one tank that has a mixed colony of cherry's (not intentionally but was due to poor advice a few years ago). We were told at that time, if they interbred they'd revert to red carrying the other colours...-bad advice I now know. So the colony began with red, black & yellow cherries,(really good quality solid coloured ones too), who's projeny all ended up a dozen shades of clear lol. This colony however, have since produced (& do so approx every couple of months) various coloured shrimp. About the only colours i don't get are black & yellow funnily enough. So we get bloody Mary's, as well as bad reds, chocolate, blue's in the blue-black, as well as the paler shade that is quite clear, orange & this lovely bronze shade, that reminds me of tarnished silver. & Of course a whole lot more clears. Occasionally there will b a clear that has a yellow cast. This Green looking one is the first time I've ever seen a shade like it. The colony has been going since 2014. I should have photo's of most of the colours, (my phone has photo's of little else other than shrimp lol) I will see if I can upload some for reference. Sent from my Elephone P8000 using Tapatalk
