"your post doesnt add up.."
Yes it does
"So, why would the little ones be the first to drop if the o2 drops and they need less o2."
Because they are young and fragile. I've seen on more than one occasion in my own breeding experience that if the O2 drops the little ones die first. (in fw and sw)
"What makes a larger clown better at dealing with the adversity? ( I have asked you this a few times)"
What makes adults better at dealing with adversity over babies in people? We are stronger and have more immunities. The flu may make us stay off work for a day or 2 but it could potentially kill the very young or very old. Its the same thing.
"Just because another vendor shipped a few clowns that didnt turn out so well, you look at those few losses, but neglect to look at the thousands shipped with less than 1% fatalities."
I don't have access to all the ones that shipped well. I just hear the stories of deaths from clowns that are too small to start with. Not just your Onyx. Many Picasso / Snowflakes are shipped too small IMO as well.
Again this is my opinion and I'm entitled to it. If you agree or not is irrelevant to me. You could ship larvae to someone as well it doesn't mean you should.
