Feeding Egg Yolk to Fish Fry

Ever wake up one day, take a look in your tank and see a horde of tiny little baby fish that weren’t there the night before? Did you have to run out in search for something to feed the new little fish? Here’s a quick and nutritious solution that you probably already have on hand…egg yolk! Yep, normal old chicken eggs that are probably already in your refrigerator. Just hard-boil an egg and remove the yolk (you won’t need the white, feel free to munch on that while you prepare the fishes’ portion). Put a small piece of the yolk in a small container of water and shake it up until the yolk is completely suspended in the water. You may want to break it up a little before you start to get a headstart but if you still notice larger chunks in the water that haven’t broken up enough, you can strain the mixture through cheesecloth or a coffee filter to get rid of the bigger pieces. Once the yolk is suspended in the water, just add a little to the tank with the fry. It’ll make the water a little cloudy so you don’t need to add much and you can save the mixture for a few days in the refrigerator.

Quick, easy, and healthy for just about any small fish fry!

    Thats very interesting. I have around 30-40 Demasoni fry and noticed they are very sensitive to most high protein food. I feed them mostly spinach, pees, carrots and garlic mixed together in a blender to a fine paste.

    Thanks for the tip. I think I will try it. :)

    how much egg yolk do you mix and how much to feed a nd hpw to store it

    You can mix as much yolk as you need depending on how many fry you are feeding and how often. Use a small plastic container to mix and store it in the fridge for up to a week.

    How much water do I add

    Just a little, maybe a teaspoon for a pea-sized piece of yolk. You want the particles of the egg yolk to be suspended in the water and small enough for the fry to consume.

    woooow thanks,will this make my fry grow faster? oh and is it okay to also feed my fry with the normall fish food?

    Healthy fish will grow more quickly than unhealthy fish. Egg yolks are rich in vitamins and nutrients which will benefit most fry, along with proper maintenance and water quality. This can be used as part of your fry diet and along with other foods that you may be feeding, but is no “magic bullet” that will make them grow large overnight.

I was one of those kids who said "I want to be a marine biologist when I grow up!"....except then I actually became one. After a brief time at the United States Coast Guard Academy, I graduated from Coastal Carolina University in Myrtle Beach, South Carolina in 2004. Since then, I've been a marine biologist at That Fish Place - That Pet Place, along with a Fish Room supervisor, copywriter, livestock inventory controller, livestock mail-order supervisor and other duties here and there. I also spent eight seasons as a professional actress with the Pennsylvania Renaissance Faire and in other local roles. If that isn't bad enough, I'm a proud Crazy Hockey Fan (go Flyers and go Hershey Bears!).
