Honestly, when I get into breeding somewhere down the road, that is what I'm going to do -- if it works in Nature, I don't see why it can't work for an aquarium.
But then again, I can't see pampering a fish that in nature it should have died anyway. I mean, think about it. We nuture the "culls" so to speak, and end up with the problem of not having any homes for these fish that would not survive in the wild anyway.
We end up with the culls that get sicker easier, and occassionally these culls are bred into the lines. Maybe we don't realize we are doing it, but by interbreeding the good strong stock with the culls, we are getting weaker fish that keel over from ich or velvet.
They don't get Melafix in the wild, afterall -- and somehow, just somehow, these fish survive despite that.
I think the American breeders ARE doing something wrong -- I have two fish bred here, and one bred in singapore, and my singapore bred one is MUCH tougher and healthier and larger than the other two boys I have.
How much does our pampering and trying to keep unhealthy or weak fry alive actually -harm- our lines?
Now, I'm not saying go out and kill the fry, but if NATURE seems to think this is the way it should go, then perhaps Nature has the right idea.
I know I would let Nature run its course. I'd be sad for losing the fry, but that is what happens.
(and of course I'd start eating fry too, if no one fed me for days on end and I was USED to having a daily diet of yummy grub. In fact, it makes so much sense that the fish get -pissy- when you miss their feedings. If you feed constantly, the fish know when their food "magically" appears. I know my fish start crowding around the front of the tank when its getting close to dinner time. It is a constant source of amusement for my husband and I.)
But eh, I would rather have 1% of the fry survive, and have strong, healthy fish that could pull through on their own than have a 90% fry survival rate and end up with fish I have to treat for some problem or another every other week.
