When nature gets it wrong...fish that thrive in captivity.

Well, White Cloud Minnows... sometimes used as feeders... are extinct in the wild

I agree with alot of this statement. One thing though, in the wild there is a natural order of "survival", or "only the strong survive". I firmly believe that a natural predation process needs to occur in order to keep the strongest, fittest around. It would be interesting to be able to track and document a tank raised predator fish like a Jag or Dovii and see how well they would do if released in there natural/wild environment.....

I agree with you, but thats more into genetics and the effect that line breeding has on the species more so than the effects of being raised in a tank or wild for a given individual.

This is why the nanny state is ruining the human race.

But does larger and "looking better" mean the fish is happier?

Larger and looking better would indicate healthier/stronger but happy? idk man happy is a relative term.

in the wild they can deal with these problems if it doesnt like one scpot. it will just move to another. In the wild they have what millions of gallons and in our tanks they have what we can supply. sure thers predation but nature can deal with it

In reference to the case of certain captive raised fish growing larger and more visually appealing than they would in the wild, how did you arrive at this conclusion?

Indeed growing to a larger size, to a certain extent, can indicate a healthier intake of nutrition in many animal species, but is this the necessarily case for the fish that are seemingly content, and, obviously, have well suited physiology, with their smaller size in the wild?
