I have some amano and red cherry shrimp in my heavily planted 40B with assorted fish. They seem to be doing fine. Want to add a different color but based on my reading, realize that I cannot add other Neocardinia species as they will interbreed.
So what other species can I try for different color. Was looking at crystal red and black but reading that they need perfect water conditions and acidic pH (my pH is 8.0). Any suggestions?
