Which will cross breed?

I know this gets asked over and over but bare with me.
I have RCS and "blue, rainbow" shrimp in together. I know these might or will cross breed and the shrimp will get ugly. I just got a batch of green and tiger shrimp from Wood and I want to know if these two can and will cross breed with each other and or if they will breed with the RCS and rainbows?
I have no plan on selling shrimp I'm actually more of a collector so I really don't care if I end up with a bunch of ugly shrimp.
I do want to have as many of each kind as possible but I would like to keep them together.
So what do you think?

Dumb question...but I have to ask, do you have the shrimp with your Discus? I'm sure the answer's no...
I don't but when I move and set up my 120g I'm going to grow all the grass and foreground plants out with only oto cats and shrimp in the tank. I want to put at least 200 shrimp in there. Then when the tank is fully grown in I'm going to put my discus in there. I have 4 adult RCS in my discus tank and they have been in there for many months. I know they could be eaten but I haven't seen it yet.

So whats the answer about cross breeding?
It depends what genus they're all from. Caridina can cross with Caridina and Neocaridina can cross with Neocaridina, but Caridina and Neocaridina won't cross.

The Tigers are Caridina (I think ~ am pretty sure). Wood's Greens are Caridina. The RCS are Neocaridina. Do you know which genus your Rainbows are from? There are shrimp from both Neocaridina and Caridina that are called Rainbow Shrimp, so until that is known we can't say whether they'll cross with others or not.
Neocardina species will interbreed with other Neocardina species and cardinas will interbreed with other cardinas.

Your new greens and tigers will interbreed. Not sure what species that "blue" is or your rainbow. The green and tigers will not interbreed with your cherry shrimp though.
While the theories expressed here are some what true, they are not 100% true. Not all Caridina shrimp will breed with other Caridina shrimp. There are quite a few Caridina spp. that will not cross with others really! Take the Caridina Multidentata for example... They will not cross with any shrimp that I know off.

And I have never personally heard of a green shrimp and a tiger breeding. They might! But then again, I have never heard of it.

Yep! Caridina can cross with Caridina, Neo can with Neo, but it doesn't mean they will in all cases.
Yup! :)

In the case that the tigers and greens did cross what do you think they would look like?
