This is supposed to be a picture showing the 3 different populations I have in 3 different bins. If it doesnt work, sorry.

All E Fetida I beleive, but the 1st bin (on the left)is standard red with minor stiping, the last (on the right) is yellow with minor red bits.. The middle seems to be a mix of well striped ones.

The yellow guys (middle and right) are in bins I inherited which had mainly shredded paper. My bin with the red ones, on the left, is fed a rich stream of kitchen scraps.

A website I was reading said that the food they eat can change their colour.

As all will be getting the same thing from now on, it will be an interesting test to see if they all nornalise over time.

Note also, of all the worms on the plate (my wife will kill me), only 1 has a Clitellum. See my previous posts re lack of Clitellum.

I think they just might all be juveniles....a population explosion a few weeks ago perhaps?

Here is a link that might be useful:
