I used to think that worms get their supply of air from the oxygen that dissolves through their skin, I remember putting an earthworm to feed my giant red Oscar a long while back and the worm escaped and while doing a water change I saw the worm moving through the gravel. It was about 2 weeks after I put it I remember. I was thinking that they would help fertilize the roots under the substrate. Thanks for your insights!johnbirg said:Hi,
Have you seen the earthworms after heavy rain trying to escape the sodden soil? Short answer is they will drown. They do make good food for big fish like Oscars and I used feed quite a few to mine when I had Oscars.
