Order a wild caught bichir and a captive breed bichirs. See which one will get to 20" or more first and which one will remain under 20".King-eL;3285544; said:Because of genetics from mass breeding.

you could easily selectively breed and get bigger animals. compare the size of some large breed dogs like mastiffs to wolves. which ones are bigger. if size was such a important factor for survival small animals wouldnt exist.King-eL;3285544; said:Because of genetics from mass breeding.

so perhaps you are
in your views.Cohazard;3285654; said:although you are correct and bring up valid points sostoudt (btw, I'm very happy to see people using scientific reasoning in their arguments), you still do not nullify King's post.
I'll tell you why:
"you could easily selectively breed and get bigger animals"
His post was based on what the genetics are like of the animals currently being produced by the farms in asia, not by what could potentially be produced.
sostoudt;3285683; said:so your answer is that asia farms are using inferior(smaller) specimens to breed. i can accept that answer.
but if you get some hobbyist breed that use big specimens as the parents, then the you can reasonably expect most of the offspring to be around the same size.
although i do think he was saying all captive breed species get smaller in mass breeding programs.
