Eisenia fetida
Stacking wormery with a drainage tap, home to tiger worms (Eisenia fetida), the classic composting worm. Set up in early summer 2026; now home to the second colony.
Feed little and often with chopped veg peelings (no citrus, onion, meat or dairy), with torn cardboard to balance wet scraps. Lots of white potworms means it's too wet or acidic: add crushed eggshell and cardboard. Tiger worms are striped red and yellow; a plain pink one is a garden earthworm that wandered in.
Most famous resident: Earthworm Jim, who has his own page in Creatures.
Tiger worms can eat up to about half their body weight a day.
Probably a few dozen worms in there, and eggs (cocoons) have been spotted, so they're breeding. Bedding of coir-type compost, torn cardboard and straw looks nicely moist. A few seedlings are sprouting from food scraps, and there are some tiny white threadlike worms, which are harmless potworms.
First colony lost during the heatwave despite cooling efforts, including refreezable ice blocks. Re-established with a second colony.
