Earthworms as fish food

[Paul B]

I have been using Earthworms as food for all sorts of animals since the fifties. (yes that was last century and the earth was here then) Frogs, turtles, snakes and a variety of other animals love worms and they form a large part of the diet of many animals.

For some reason we as aquarists rarely use or even discuss this great and "free" food and IMO one of the best and healthiest foods out there.
Besides worms having the proper nutrients. They also contain soil and soil is full of bacteria. I feel this bacteria is sorely needed in this hobby because the vast majority of food we use is commercially packaged and sold as food. There is "almost" nothing wrong with commercial fish food, I use commercial frozen food myself but commercial food may have one huge problem. It usually has no live gut bacteria and gut bacteria is what makes almost 100% the immunity of fish. Yes, many commercial foods contain Pro Biotics and that is for another thread.

If you read any of my threads (no, you don't have to) I am very big on gut bacteria and how it is vital to immunity. I believe that is also why this week my reef made it to 53 years old and nothing in my tank has ever been quarantined or medicated for at least the last 45 years.

Just two days ago I took my morning walk in the rain. There were worms all over the place which is unusual for the wintertime in New York, but it was warm. I collected 5 or 6 worms. I have 3 Red Waspfish and they are finicky eaters and many times are just to slow to get any food. They are predators and can eat large food so don't have to be fed every day but they do have to eat.



I chopped up a worm into half inch pieces shown below.
Using one of these, I shot a worm near my Waspfish and he immediately "woke up" and sucked up the worm. Normally I have to hit him on the head with a piece of clam multiple times to let him know it is feeding time, but earthworms, blackworms or I imagine, any worm makes them go crazy. The biggest problem is keeping the other fish away but using that "baster" that I made, I can just about put the food in the fishes mouth.



Earthworms are also excellent food for anemones and crabs. I can't think of an aquatic animal besides pipefish and seahorses that won't eat worms.
I can and always have depended on worms for hard to feed creatures and they are almost always available and large amounts of them can be collected and kept for long periods of time as long as they are kept damp

Abstract​

Earthworms have been a traditional medicine in China for at least 2300 years. Because of medicine food homology in China, people have been using earthworms as a food for several centuries. Earthworms are rich in protein and various amino acids; the protein content of earthworm meal was 54.6–59.4% on dry weight. Their protein content and amino acid composition are better than those of fish meal, cow milk and soybean meal. The crude fat content of earthworm meal was 7.34%. Earthworm protein is easily hydrolyzed into free amino acids. The hydrolyzed body fluids contain 9.34% protein and 78.73 mg of free amino acids per liter of raw fluid and are rich in vitamins and minerals. By the fast development of molecular biological techniques, more Verm pharmaceuticals and functional components were isolated from earthworms. An antibacterial peptide and a functional earthworm powder were introduced in this paper. In short, based on its nutrient content and functional components, earthworms could be an excellent raw material source as homology of medicine and food for human use, especially as functional food in the future.

Now this guy waits for the "baster" and keeps biting it until the worm comes out.

Your fish looks amazing Paul


I wonder, if you feed or tried white worms too? I have a white worm culture that I feed to my freshwater tanks. Would it make a good food for juvenile clowns?

Do you have any experience on that one?

Lennie, good morning. My whiteworm culture is about 12 years old. I use them all the time. I lost a lot of worms because they froze here in my garage but their numbers are coming back. They are an excellent food for anything that will eat them.

Thanks Paul. I feed it twice a week to my other fish. They are everyones all time favorite

I will keep that in mind
