IPA: //ˈtjuːbɪfɛks//
KK: /tjuˈbaɪfɛks/
A type of small, thin, reddish worm that lives in freshwater and is often used as food for fish in aquariums.
Aquarium owners often feed tubifex worms to their tropical fish for added nutrition.
**Tubifex** → The word is formed from "tubi-" (from Latin *tubus*, meaning tube) and "-fex" (from Latin *facere*, meaning to make or do). The term refers to organisms that live in tubes, hence the name 'tubifex' means 'tube maker.'
Think of 'tube' ('tubi-') and 'maker' ('-fex') to remember that 'tubifex' refers to creatures that create or inhabit tubes.
