Well I figure it like this ... Lucky was a feeder fish (the kind pet stores sell as live food for other critters); his life was set up for nearly no time at all being alive; he has been with me for about a year and has gone from around 1.5 inches long to about - oh - 7 ish inches long. He seems to be really strong and healthy and is quite liking the big tank and all the room (next to none of the plants made it back into the tank for fear of them carrying whatever it was that was so wrong before). He was on my dresser, but now I have him on a wheely cart thing right by the window ... he seems to like it there ... maybe its the natural light.
