I would disagree over a large part of evolution being hybridizing. Just look at the current aquatics market - almost all of these hybrids would have had no chance of meeting up in their natural habitats. Speciation is not usually (or perhaps better put, rarely) such a random act. Just look at the rather large populations of obviously closely-related species in Central American rivers, yet there are NO hybrids between them found in those river systems. Most of speciation thus far described had to do with small behavioral or morphological adaptations/evolutions giving a competitive edge, and these inheritable characteristics being passed on to offspring. Just look at the genus Herichthys to see speciation in action! {although such roadmaps to speciation are not all the same, to be sure}

You're right. I didn't mean that hybridization was a large part. Natural selection is the hands down driving force of evolution. I meant that it may have played more of a roll in certain species, but it would definitely be a very small or even negligible role overall.

Ditto here, I think there is no absolute. I've read some accounts that many of the larger gaupote hericthys type fish actually do hybridize in the wild. And for flowerhorns, they're actually will survive and might be able to out compete their wild cogenere.
 
love this thread.
i have nothing to contribute i guess...
we have flowerhorns surviving and thriving in the wild here btw. ;)

I went through every single page of this thread and looked at every single picture as well. There is no way someone will read all the comments in this long thread. Although fugupuff have very insightful and informative posts. By the way, where is fugupuff's store? I might drop by one of these days to meet the man or at least check out his store.
