I just acquired some blue tiger shrimp. So I'm just curious if they will cross breed with Green or yellow Caridina?
I know this thread a month old but I wanted to chime in. I have kept tiger shrimps with green shrimps in the past and I never had them crossbreed. Even though they are both caridina, they look very different in shape. Tigers are Cantonensis and the greens I kept them with were Babaulti. I kept them together for a little over a year and they each kept having babies. Only major problem I had was that its hard to tell the babies apart when they are 1/8 and under but the tigers grow way faster then the greens. And the greens have the tiniest babies I have seen from dwarf shrimps.
Since I started the dwarf shrimp hobby back in 2004 I have made many mistakes and learned alot of things the hard way. For instance tigers and crs will for sure crossbreed and it didn't take them very long to mix it up. Tough lesson learned back in 2005. I'm thinking of setting up another tank with both tigers and greens again just to see if it was a nothing more then a lucky fluke. I don't think they will cause right now I have a few bumble bees (Cantonensis I believe) with some greens (Babaulti) and so far no crossbreeding.
They are together cause I have no choice due to space limitations. Greens have greens and Bumble bees have bumble bees. There are other Caridinas that won't crossbreed with each others... but so far almost every Neocaridina will crossbreed with other Neocaridina.
For the record I have never sold nor given any crossbreed shrimps away. They have gone into my 125g planted tank where CPDs and Cardinal Tetras take care of 90% of any babies shrimps that are bred there. Also I don't encourage anyone to crossbreed shrimps.
