I have a little stack n store type box, loose fitting lid in blue plastic. In it I keep dendros and lobs, it actully sits on my large tank. I just used the small amount of soil that came with the worms. Then put shredded paper that I give a couple of squirts from a mister bottle, and feed them, plant bits from my tank, I tend to empty tea bags onto it, carrot pealings, parsley chopped, peppers Finley diced. There breading so well that I have even been feeding babie worms to the 2month old hatchlings. Although not often as the tiny ones are hard to find.
Have had to take a load of the worm soil out today, then had to go through it all for the little egg type things. Ah cocoons (couldn't think of the word then
)
So I could put them. Back in. Think I will have to up grade to a larger box soon.
I thought I would throw my tub of lobs in with them as a kind of holding tank, even though I had read they either like it cold, or you had to get special food for them, but they seem to be thriving as well, wether that's because they eat what the dendros make or they eat the pealings or stuff I don't know. But so far all is well in my little worm bin.
(it's only about the size of a shoe box)
