I was just reading the glo fish thread, and it made me wonder. How DO they get those artificial colors into "painted" tetras. Does it involve physically grabbing them and injecting them with a needle containing the flourescent compound, or is it somethign to do with the eggs or genes, or putting the chemical into the tank and letting it absorb??? I was never told exactly how this is done, and I was under the impression they were forcefully injected which is why I never bought them...even at age 7, when bright colored fish were my thing. But it doesnt seem practical to inject each fish individually, so I'll wait to hear the truth.
