Protein content for cories?

  1. aylad Well Known Member Member

    I've been advised to feed my peppered cories some high-protein food. After looking at several foods, I'm wondering what the actual protein content of "high-protein food" should be. Can y'all check your nutritional information and share what the "crude protein" or whatever is?

    The best wafers I've got right now yield 43% protein. NLS Thera+A, which I use as a staple for all my fish, has 38% protein. The wafers I originally started with have, I think, 35%, and the shrimp pellets I found at Walmart today -- which are recommended specifically for catfish species -- contained something like 30%.

    So... what's in your bottom-feeder fish food?

    Thanks :)

    just give them some frozen bloodworms. They'll love it! Meaty, cheap, readily available. The NLS Thera+A pellets are great btw.

    I am waiting to see the diet results ... since to much protein can also hurt your fish. Keep me posted

    It isn't so much the percentage of protein, it's the right kind of protein corys need, their main diet should be live or frozen food such as bloodworm, brine shrimp, daphnia etc along with a catfish pellet, the shrimp pellets would be fine for them

    I use home made food. 25% pea base, 60% spirulina (protein~28%), 5% beef heart, 5% paprika, 1% gelatin, 3% spinach, trace amt of. Vitamin b12, garlic juice, vitamin k, calcium.

    Corys get little to no nutrition from vegetables as their digestive system isn't set up to process it efficiently.
    Fatty food like beef heart can also cause liver & kidney problems if fed too often.

    Funny you say that bc. Bloodworms, brineshrimp and fish meal are even higher in content of protein/fatty foods or low nutrition at all

    I'm just saying what I've learned from leading cory experts that beef heart is not good for corys, it wouldn't be found in the wild whereas other live foods would be.

    Right then, thanks! :) I'll pick up some of the shrimp pellets and keep feeding a variety of foods in the meantime. It's good to know that several of the foods I've been feeding have enough protein to keep them healthy.

    Agree with Coradee again (sorry hahahaha) Think variation is the keyword and mainly "meaty" food instead of vegs. But they like to eat blanched lettuce, spinach, aso. Beefheart-overfeeding often occures with Sterbai "under" Discusfish fed. Some of those fish show "fatbubbles". Don't know the 5% in this food will cause this as well.

    Sorry DoubleDutch but corys get nothing from veg.
    These are a couple of quotes from Ian Fuller, posted with his permission

    "They do not have teeth for grazing so green foods are of little use, they may be mouthed, like they mouth the bio film that forms on all things submerged searching for micro organisms, shrimp and larvae and the like."

    "Corydoradine fishes are basically filter feeders and may graze over living algae growths searching for the microscopic life that breeds and grows in it, but they are not equipped with teeth for scraping and removing algae, their gut are also not equipped to digest it. So algae based foods will be absolutely useless, even if people think their Corys are eating it they are not. If there is nothing else they will mouth it and may get a little something from the binding aged, but that is all".

    I know about algae, but defo see them eat from blanched spinach, lettuce and aubergine. Possibly goes straight through the intestials, but who is eating this in my species only tanks. They "fight" over spirulina !

    Double Dutch is correct in saying " They "fight" over spirulina ! " However plant protein is not equal to animal protein by way of structure, but the highest of the plant world we can see in fish food. Coradee is also correct in that it involves the stomach structure... So to ref the original post, it should be placed on animal protein content ( and that also varies ) with whole fish meal and fish meal. Nice question, Thanks !
