Whats the difference between Zebra and Tiger shrimp

If I had to pick one it would be the tigers. I have kept tigers the longest.

However,

The tiger shrimp and NSIZ are both breeding well. I have young of various sizes in both of their tanks. There is a berried striped IZ in their tank. She is very shy and stays in the moss or other plants most of the time. The rest of the striped shrimp I have are juveniles that I purchased recently. I don't have any babies that I raised of the striped variety as of yet.

Both varieties of IZ grow slowly compared to other shrimp I have kept.

Good looking shrimp, which one breeds best for you?
