Your opinion, and your entitled to it.I have kept fish , fresh and salt for 40 years. Once a day feeding does not make for a weak fish. It is also what you feed. I feed flake, pellets, frozen, live... They do not need as much food as most fish keepers think to be healthy. In fact, over feeding is not doing them any favors.
I'll refer to experts in the field, and what I have done for the better part of 40 years.
Fish eat all day, every day in the ocean.
