Don't Gars and Bichirs predate on live fish in the wild?
It would seem if you have a tank, made to simulate a natural habitat that the feeding process should be somewhat close to natural no?
I understand everyone has different opinions though.
Each generation imagines itself to be more intelligent than the one that went before it, and wiser than the one that comes after it.
It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is the most adaptable to change.
