So I tend to believe that in general even if we think we're overfeeding, we're not, not really anyhow. Yes it is true that as long as they see food they will eat food, so we can't use a "they'll stop eating when they're full" sort of thing to figure out how to throttle back the amounts, but the flip side is although they'll never really be "less" hungry, they can be "more" hungry and that can sometimes lead to aggression. So it's a fine line or a balancing act, maybe with some experimentation and observation you'll find the balance that works for you.. |
I think we were typing at the same time and essentially saying the same thing.
If you see these fish in the ocean, you realize a majority of fish we keep are underweight and on the slim side for fish with no competition for food or predators.
Many feeding all throughout the day is best for tangs. All they do is graze all day in the wild.
