I have Red Cherry Shrimp in my 10G and I was wondering what other colorful shrimp could I get that won't cross bred with the Red Cherries?
If you don't want your RCS to crossbreed, you're limiting some of your options. May I ask why you don't want them to interbreed?
You could try some different colors of Tiger Shrimp or Amano Shrimp if you don't want them to interbreed.
If you don't mind interbreeding, there are yellow shrimp, blue pearl shrimp, and snowball shrimp.
