There’s an interesting new inhabitant in the Shrimphaus, what looks like a spontaneous mutation in the bloody mary shrimp lineage. Bloody mary shrimp are generally a solid translucent red throughout but this little fella (I think it’s a boy) is mostly clear and colourless, except for a red head, red stripe just above the tail, and one red horizontal back segment. This is the “rili” pattern, and is reasonbly easy to find in red cherry neocaridina shrimp, but there isn’t much information on ‘bloody mary rili’ shrimp. The eyes seem to stand out a lot more as well. I think this is because in the usual bloody mary shrimp the eye region surrounding the black pupils is reddish pink, whereas this googly eyed individual has completely white surrounding tissue.
Bloody mary neocaridina shrimp have a reputation as being reasonably genetically stable, so this seems a little unusual. I’ll keep a look out to see how this one develops – I’m not actually certain it is a bloody mary shrimp – and whether any more different and interesting mutants come up.
