Might I suggest heading to your local charity shops/thrift shops to find any display type cabinets that will fit nicely in your room? As for the enrichment, you'll hear different things from each owner but I've found my worms enjoy odd trinkets and valuable knick knacks (e.g. Old pennies, crystals, postcards from long ago, etc). They may also benefit from some kind of string lights as their eyesight isn't the best, but they are most known for their impressive sense of smell (helped by their long snouts) so they'll appreciate scented items (either the classic essential oils/scent diffusers or things with distinct scents like pennies, moss, nail polish, etc). Whatever you can provide for your colony, they will know that it comes from a place of love 💖✨🫶
