Scientific name for trout worms

[merk199]

Anyone know the scientific name for trout worm? I suspect trout worms are aka red wigglers. I would like to get the name so I can buy a lb or so for vermiculture/feeding my newts. Without the scientific name its hard to figure out if I am buying the correct worm.

Thanks

I think they might be European nightcrawlers (Eisenia hortensis, formerly Dendrobena hortensis). I am guessing this based on their size - somewhat larger than red wigglers.

If you are buying a pound, the seller should be able to tell you if they are red wigglers versus European/Belgian nightcrawlers.
