Who here uses or is familiar with compost / earth worms in their vivariums? Aside from great substrate filtration, they tend to lay excellent sized eggs for some of my wee sized obligates And provide great compost tea for my bromeliads...

tiny red worms ? The Salamander crowd uses some cool tiny 'earthworm' sp.

I have two tanks that have them. I don't know how they got in there but they are there now lol. These tanks are 2+ years old though too.
