you know what....thats what ive always been thinking.
how do fish grow so much if nothing we feed em has calcium?
jamesliu2000;2790393; said:I was thinking about the same thing, too. Then I look back at those frozen food ... for example Hikari frozen krill quote from manufacture:
"
Hika** krill is an ideal dietary supplement for larger freshwater or marine fish. Also an excellent color enhancing diet. Three-step sterilization ensures unequalled product quality - no harmful bacteria, parasites, or foul odors. Fortified with multi-vitamins. Packed in pure water and available in convenient "no touch" cube packs or flat packs. "
SEE.... without that extra mineral and vitamin... just nature krill or shrimp from the market is going to stunt your fish. Exoskeleton is NOT source of calcium. They are keratin.. protein product.
Just my thought.... no intention to change anything here.

in the wild i mean...
its not like someone throws hikari into all our rivers....
jamesliu2000;2790420; said:The only animal that exclusively eat shrill or shrimp that I can think of is blue whale.... those marine animals have extreme efficient kidneys that they can filter hypertonic salt water... meaning they can drink salt water and still able to filter out extra salt in their urine....... we human can't.

check out salt water mineral content.... calcium and phosphorus are in there
Vitamin drink for those animals..
