I'll go first:
In a nutshell, my bin is two 18g rubbermaid bins nested inside of each other (only the inside bin has a cover).
I drilled really small holes in the sides, top (lid) and bottom to allow some air circulation and to allow fluids to drain from the inside bin (into the outside one)....Drill them small enough that worms can't also "drain" through... I added some plastic yougurt cups to keep the inside rubbermaid off the floor of the outside one (allows fluids to drain easier).
I've been feeding leftovers of what we eat: some pear and apple cores, some banana and mango peels, even some junk mail and paper towels (shredded).
The easiest way for me to use the worms is to keep a plastic cup by the bin (in the garage) and whenever I add stuff to the bin (or go into the garage), I just take off the lid of the bin and grab whatever worms are hanging out on the sides. Quick rinse in the utility sink and they're fish food.
I feed them to all of my fish...but have been giving extras to some acaras I'd like to breed...and some pikes, which go bonkers for them.
How about you?
