Once again, fish are opportunistic feeders. However, it isn’t because the fish rise to the surface of the tank each time one walks buy that one needs to feed them. The importance lies in the quality rather than the quantity. Contrary to popular belief, fish don’t need to eat as much as we think and there are several reasons for this. First and foremost fish unlike us don’t need to spend much energy in fighting gravity as they evolve in a three dimensional environment. Second reason is that fish are cold blooded animals and don’t spend any energy unlike us to keep warm. Third reason is that humans spend lots of energy in producing urine fish just produce ammonia. But last and not least, our fish evolve in an artificial environment however large the tank may well be.
