How many calories do our fish need?

[Daniel62]

So after doing a bunch of reading on here, I started to feed my fish a lot more food more often. My fish have never looked better.

Now mind you I am watching to see that most of the food gets eaten, before feeding again a little while longer. I am not seeing a lot of waste. It is a mix of dry and frozen.

And I cannot believe the amount of Nori my tangs are eating. Almost a sheet a day sometimes more. 1 med tang and 2 small tangs. Also the other fish who are chowing down on this has really surprised me, especially the dwarf angels.

So if you compared what I was feeding in the past to now, I was really starving my fish.

So my question is, how many calories do fish need each day to be really health, and can we make them too fat? I looked at all of my different foods and I see nothing about calories, only % of certain type of protein etc.

So what are you thoughts?

How much were you feeding before?

 

[Daniel62]

About 1/3 sheet of nori, 1 cube krill and a pinch of flake or pellet. Now I am feeding 1 cube krill, 1 cube enriched brine, 2 or 3 pinches dry and a cubes worth of reef frenzy.

Is that daily?

 

[Daniel62]

yes

Depends hugely on the species your talking about, whether they are omnivore carnivore etc, what your feeding, how much flow there is in the tank etc so I doubt you'd get a figure.
Predators for instance eat a large amount infrequently but the high metabolism of an Anthia needs plenty of grub.

You normally see a % body weight figure as a guide but like you say depends on the type of food.
