Earthworms got their name from their habitat and their duty in the animal kingdom. They live in the soil and eat roots, rotten plant pieces, fungi and fruits and convert them to fresh, mineral rich soil when they defecate.
They commonly grow to a size of less than 3 inches, but some of their species can grow up to 14 inches and are usually seen above ground at night time. They can dig as deep as 2 meters and are best known as fishing bait.
If you decide to observe them in the house, you should fill a small to medium sized fish tank with fresh, moist but not too wet soil and find some worms by gigging in the garden, forest or a meadow. You should find some instantly in the first scoop of soil.
Keep the soil moist, to assure that the worms won’t dry out, but not too wet, because they can drown.
They will dig little tunnels in the soil and you can observe them eat all day and night.
You may want to feed them rotten leaves, fruits and even egg shells (to provide them with a vital source of chalk), but please make sure that the food you feed does not rot in the tank. Certain kinds of fungi are harmful to them.
These are pet I can recommend to children and adults of all age, who want some insight into nature’s hidden underground activities.
