Thanks for the input.

I'm really enjoying attempting to get a handle of the behavioral differences between the different ssp. I think many people think all milks are the same, but who can blame them when so many in the hobby really are just a melting pot of stuff. it'll be interesting to see if the differences I notice hold true as I get more experience with different animals as I'm only working with pairs for the most part now.

I like that leaner rock idea. I think I'm going to try that out of a few things.
