lol, these guys are some of the fastest growing fish I've ever seen. When I had mine, I think they nearly doubled in size within about 6 months, if memory serves. The best thing is that they will eat ANYTHING that lands on the bottom of the tank (or floats, come to think of it..) I used to feed mine sinking cichlid pellets, bloodworms, algae pellets, frozen whitebait (they go insane for this) and I loved to hear the clicking noise they make when they peck at their food. Really awesome fish, wouldn't mind going back to them again someday.
