not sure if you would get the same results in the wild as you do in selective breeding in a tank as selective breeding is following a certain trait i.e colour or body shape and then trying to breed that trait in
as for the yellow tail being fertile i would very much doubt it is same as parrot fish are not belived to be fertile but i could be wrong

Hence why I termed it in 'centuries'. I see it is purely a matter of probabilities. In the wild, the contributing factors are reducing them. In the tank, it's the other way around.
As to your articles. I think the Livebearers again, have that high reproduction factor going for them. With such a high generational turnover, even in the wild, hybridization must be occuring with reasonable frequency. And as I said previously, I believe that two species that are able to produce offspring, must share a common ancestry anyway.
As to your articles, I've probaly said it. I think the parrot fish looks deformed, if not 'injured'. The Flower Horn is quite an attrative fish.
Although there is something to be said for the argument, claiming that we're trying to be God. If a species exists right now, it's because it's weathered any adversity that has 'removed' those that didn't make the grade.
If we produce hydrids, there's evey chance they've already occurred in the wild, but weren't up to it. I like the idea of breeding in the hobby, and in the hope that we don't completely screw up the wild, there is always that possibility, that we'd need to restock wild habitate from our collective tank stocks.
The hybrids won't cut it. Their natural habitat, is your Lounge.

when i started this thread i thought it would evoke a whole lot of different thoughts but what i also wanted to know was how other people viewed the subject i already knew that most livebarers had been subject to this practice i just wondered if people realised that there was more in the hobby than they realised, yes gary you realise you have hybrids in your discus most discus that you find for sale are hybrids it can be very hard to find the two true species Symphysodon aequifasciatus & Symphysodon discus, here is another link to follow which i found very interesting reading (i know i need to get out more often )

but since i started this thread i have learned that there is a lot more hybrid fish than i first thought

i dont have much to add to this other than i heard that someone tried to cross a crocodile with a fashion designer - apparently they wanted to breed a snappy dresser

i dont think my views have realy changed much since having read as much as i have on the subject just reacently i do know that some people view it as a crime shock horror ! where as other people just dont care. i think i would probley fit in the middle as yes i realise that most livebarers fit into the catogary also i did'nt realise how much it happened in cichlids, oh and dont forget i have a hybrid but was that by choice or ?
dance now where ever you may be

It was good discussion.
I was surprised to find some of my thoughts reflected in the articles you brought forward. But maybe my Biology background influenced how I percieve some of those things.

What are you up to, digging out all these old threads? You got bored with no one around, didn't you?
I studied Biology for several years at secondary and tertiary levels. So apart from disecting things, I have a reasonable grounding on how critters are put together down to the cellular level, and some sub-cellular detail.
I vaguely remember doing some enviromental stuff. Evolution, and some basic genetics - Gregor Mendal(?) and his peas.
I'm actually toying with the idea of getting back into it, and doing some Bio-Technology subjects part-time. Could be fun. Now that the kids are getting into secondary school, my interest has sparked.

Some of the stuff they bring home, I'd swear I didn't cover until a couple of years higher. Occasionally I get some that I have no idea at all !
My youngest was busting for a Microscope a couple of years back. I bought her a good one, high end secondary / tertiary level quality. I didn't want to waste money on those toy things. Beside's, I've always loved playing with Lab equipment.
Anyway, I've got an old color video surveilance camera, for which I plan to construct a mounting bracket. Then I'll be able to feed the Microscope image into the computer.
We could could go a whole new 'what's in your tank?' catagory...
