Well, I was waxing wishful. And since we're talking genetic engineering, I was thinking more along the lines of a fish that ate waste and converted it into something beneficial, or in other words, his waste wouldn't be wasteful. Say a fish that ate other fishes' waste and its own waste was pure nitrogen, oxygen and CO2? Great for a planted tank! How likely is it? Not bloody likely anytime soon, but the way science advances...Aqualung said:
