If it is cool all the beter. When I bought a package I was told they were RCS, CRS, And some Chocolates. They were shiped the water was murkey and I lost some on the way to my house. Most I can tell that survived were RCS, and some that I would call low grade PFR. Take a look at my photobucket and let mr know what you guys think I have. I will start to selectivly breed as soon as I have space to do so.
