Hybrid black rose cherry shrimp

Due to blue and red are co-dominant traits for cherry shrimp, I obtained hybrid black rose cherry shrimp by breeding blue dream males with fire-red females. Yet their offspring have blue, red, and black/dark color. Then how to keep this hybrid line? Based on Mendel Genetics and that blue and red are co-dominant traits, I can simply keep hybrid black rose, together with their offspring, including red, blue, and black rose, in the same aquarium. Any breeding among blue, red, and black rose, will only result in blue, red, and black rose phenotypes theoretically. By removing any undesired pale color ones from breeding, I will be able to keep black rose, together with blue and red in the same aquarium forever. What a colorful cherry shrimp aquarium!
