[Killietalk] Wild vs. tank raised
"If we are talking about tank raised fish verses wild fish there are probably conditioning factors to consider. I understand it is very difficult just to keep wild caught fish alive in an aquarium much less breed them."Probably too sweeping a generalization. Having collected wild fish (goodeids), I found them trivially easy to breed in captivity, spawning within days.
I've never kept wild killies, but anecdotally I've heard some species are very aggressive once in captivity, though they breed readily. I'd certainly enjoy the chance someday at some neat wild killies.... hmm... maybe that's why I'm in the AKA :-) Have definitely heard that fertility drops off across the generations and of course, coloring might change due to who knows what. Barry's talk a few years back on N. rachovii and how it looks the same now from the wild as it has 30 years in the hobby (I think this was the Mafia Island strain) of course means, you can't generalize...
