Hello Garth,
I found this on an American Web site
(The European Nightcrawler (Lumbricus rubellus) is larger than the Red Wiggler (Eisenia fetida) but smaller than the Canadian Nightcrawler (Lumbricus terrestris), making them the ideal bait worm. They’re also tougher, staying alive longer and much more active than other types of fishing worms. European Nightcrawlers are the only earthworm suitable for use as bait in brackish salt water.
Europeans are more heat tolerant than Canadian Nightcrawlers and more cold tolerant than African Nightcrawlers. When kept at 70˚ Fahrenheit, Europeans will keep alive and healthy from three to five weeks. At 60˚ Fahrenheit, they’ll keep even longer. In beds, they do well in temperatures ranging from 50˚ to 90˚ and can tolerate temperatures much higher or lower if their bedding is of the proper depth and moisture content. The ideal temperature is 51˚Fahrenheit. pH is of particular importance: a range of 5.5 to 8.7 is acceptable but they prefer neutral (pH: 7) soils.
European Nightcrawlers (Lumbricus rubellus) are usually reddish brown or reddish violet. They have an iridescent topside and yellow bottom. They have 95 - 120 segments and are usually three to six inches long. They prefer high organic content bedding.
Europeans produce about one egg capsule per week, if kept within the optimum temperatures and fed well. If they are not too crowded and are happy, they will breed faster. )
Now I am not sure exactly which worm is the European Night Crawler, Lumbricus rubellus or Eisenia hortensis.
I have Lumbricus rubellus but not in large enough numbers for sale just yet. They are really good breeders and as you can see from what I pasted above are a excellent fishing worm
