WC or CB?

I like them both. With wild caught you can grow them big. While captive breed won't grow as big as the wild caught. However when it comes to variety of patterns, captive breed stand out more than wild caught, but there are captive breed as well with not much patterns on them.

If your a person who don't have a bigger tank due to limited space, then a captive breed is the right for you. They are cheaper as well and are available in may LFS. If your a person who's into bigger fish, then a wild caught is the right one for you.
 
why wont captive breed grow as big? that seems like a myth to me. unless ofcourse it a dietary thing but you can change the diet.

Because of genetics from mass breeding. It's not a myth, it's reality. Try it yourself if you thinks it's a myth. :screwy: 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".

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.

genetics are the luck of the draw. you could easily get ones that could be the same size or bigger. i dont think the size would matter much after a certain point, once a fish is to big for most predators. size could even be a disadvantage if you require more calories then you could obtain in the wild.

humans would fit your description of captive bred, since we have treatments so even weak ones survive. yet im 6 foot 3 inches. humans have been getting consitently taller over generations. 150 years ago the average height was 4 inches shorter. some experts believe it has do with a change in childhood nutrition, so perhaps if you feed the baby bichirs more they would be bigger.

:grinno:so perhaps you are:screwy:in your views.


and bam reason and logic will always beat myths

with fish it could also be nitrate and flowrate too
 
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.

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.

You're right, he was speaking broadly/generally, based on what is going to be encounted by the hobbyist. I see how you could interpret what he said in a different way.

I have no knowledge of what the breeding stock is like for those farms so I can't comment that they are using small specimens, but I do know that they rely on hormone injections to get the spawns.

You are also correct about selective breeding as I alluded to earlier, so wouldn't it be nice to see more hobbyists successful in natural captive breeding?
