I think a few fancy imported shrimp lines would end up being a lot less expensive in the U.S. after some fun little experiments like that. (Obviously not less beautiful but definitely less spendy)
3. Yeah keep culling and youll get there. If you think you have pure lines and ever wanted to test them for line integrity, simply take one of your pure line shrimp females and put with a golden male. If any offspring are goldens, you do not have a pure line (since the golden gene is recessive).
