When Bob was adolescent he sometimes regurgitated
Eisenia foetida/fetida but never
Lumbricus terrestris. Now he is 11 inches long and eats anything that moves and shows no preferences. He follows people around his tank as they walk by, has a go at fingers etc.
For variety I also feed lots of woodlice (mostly
Oniscus asellus and
Porcellio scaber). Interestingly the only living thing I have seen Bob spit out is Armadilidium vulgare - presumably he mistakes them for stones or seeds which is of course just what this type of woodlouse intends!
By the way I only use
Eisenia when I can't find any adult Lumbricus (eg. dry or very cold weather) because I have an endless supply from the worm bin - but these are not organic due to supermarket kitchen waste, paper and cardboard with ink etc that the worms eat. Incidentally when they were tiny I fed Bob and his siblings lots of the tiny white
Enchytraeus buchholzi or
E. albidus from the worm bin + baby woodlice. I assumed that the reputation for these as fatty food came from the commercially produced ones which I think are fed on milk and white bread?? but I don't know for sure - does anyone here know the nutritional value of wild
Enchytraeus.
