I am a bit confused as to which worms are actually Red Wrigglers, Eisenia Foetida or Lumbricus Rebellus. Some websites refer to one or the other as Red Wrigglers. I was under the impression Eisenia Foetida were Tiger Worms and Lumbricus Rebellus were Red Wrigglers.
From my observations and researching different websites I am sure I have Lumbricus Rebellus. I was told they are Red Wrigglers. I don't want the Tigers as they give off an offending substance which repels fish but I believe from what I have read that they are a superior composting worm. I supply a local Pet Shop with worms for reptile and fish feeding and don't want to risk losing this market buy introducing Tigers into my beds then finding the reptiles and fish reject them.
Soon I am going to purchase Indian Blues (Perionix Excavatus/Spenceralia) , apparently an Australian native. They grow up to 6 inches long and are the fastest breeders with up to 18 worms per week. They also consume much more food than any other worm.
