Cutting up worms

[mpmistr]

Metal scissors are perfectly OK. Metal scissors inside your tank, not OK.

[Louis Charles Bruckner]

making sure that the scissors are clean will help the worm recover from
the diesection of the end that is furthest from the Clitellum ( the bump in the middle of the worm.)

The worm will heal and live verses if you cut from the other end.
