I'd imagine that the "rotting" food will simply kill the words.
If you want to create a "wormery", this is what i used to do.
Cut the top off of a fizzy drinks bottle (ie. coca cola, sprite) (Other brands are available

)
Poke a few pin holes in the bottom to allow for drainage.
Fill with a few inches of soil, a few inches of sand, a layer of leaves/veg scraps/grass then repeat til full.
Top with a layer of potatoe peelings, fish pellets, compost, dead leaves, anything veg and dead really.
Throw in a couple of nice big worms (heres where selective breeding comes in)
Cover the top with a black plastic bag (corners are ideal) cut an air hole in there. pop somewhere dark. Water with about 1/2 a liter once a week. In about 3 months you should be crawling with huge worms.
Just take the black covering off, and they'll be there for the picking.
(the sand/soil combo results in huge worms, it is said to aid digestion.)
There we go.
Hardly about cichlids but there is the yorkshire way to grow worms
Hope it comes in handy.
