Hi All! Thinking about getting some shrimp for my 29g in the future. I was all set on getting red cherries but I've since seen the mandarin and some yellow ones. Is any one better than the other? I've researched some and they appear the same. Could I get a couple of each? If so, would they cross breed? I'm wanting something colorful, my stock is 6 Von Rio (flame) tetra, 6 black phantom tetra and 4 spotted Cory cats. I'm thinking about getting some Kerri tetra from severum also. I have black sand for substrate. Thanks!
