Would you consider an emaciated extraordinarily reduced patterned clown to be high quality?
That's why I chose that there was not one single aspect to the quality.
I am extremely picky about the animals that I add to my collection, including the normals. I choose my normals based on their colors and patterns as well. For example, I only pair my pastel with my lightest females, those that also have nice blushing heads as well. He doesn't get thrown in with just any female with the goal of "just" producing pastels. I also want to produce the nicest examples of the morphs that I'm working with.
I also agree with Deb and Deborah - there are also some people who I would never do business with, no matter how nice their animals may be.
As to temperment? I'm less concerned about that. I think a lot of temperment also comes from more than just genetics. I have been bitten by my adults, less than 5 times, and each time, it was because I was careless and startled them.
However, my friends Deborah and Ed (Freakie Frog) both seem to get bit on a higher frequency than I do. One theory that we've come up with is that both of them have a higher body temperature than most people do. I sat at NERD holding a black pastel, calm as can be in my hands. Deb comes to sit next to me and it starts swinging at her. We did "temp gun" Deb and she was giving off more heat than I was.
I believe that Ed has also temp gunned himself and he also gives off more heat. He has a female of mine on loan that has NEVER bitten anyone - until he got her. Now she likes to play "let's see how fast Ed can move" with him.
Of course this is just our own "theory" on why the two of them get bitten at a higher frequency than other keepers do. Both are confident handlers, the only difference that we can discern is the amount of body heat that they give off.
