Calceo shrimp

[ineke]

I can’t find out a lot about these shrimp but suspect i have a lot of them except to me they are culls. I started getting Bee shrimp hybrids that had little or no white on them just their red or black stripes. During the last few years while i was out of the shrimp breeding i kept seeing these Calceo shrimp but no write up on their breeding. Can anyone tell me more about them . I have a few photos of mine but I’ve always culled them . I’m keeping these to add some red into my line. Would these be Calceo?

I’m no expert on specific caridina lines, but I’ve seen these calceo shrimp around. I think your first image would be considered a calceo, while the second would be a bit more of a fancy red tiger (CRSxTTs). At least in my relatively uneducated opinion. They’re certainly cool shrimp. If I had to guess, I’d probably say the ones that are sold are some sort of line bred morph of fancy tigers, with tiger, crs, and maybe some bee heritage. I can’t see that the commercially bred ones would be crossed back to any particular line, so they probably don’t have wonderfully strong genetics. Again, this is purely speculation. 
It’s pretty interesting that you’ve had some crop up in your tank. Is it just bees, or do you have tiger lineage in there?

Because they were originally crossed with Tibee they have Bee and Tiger genes. Then I introduced Taiwan Bees to get Taitibees and much later I introduced OEBT to some and Tangerine Tigers  to others hence my affectionate term “ mongrels “ because they have a little bit of everything.

 I have had numerous shrimp in both black and red that didn’t have the white colours so eventually culled them out. I had fancy Tigers types as well . I put a lot of them outside and only recently started using them to try and get more females. 
Here are a few that I got initially and eventually they completely lost the white
