Lumbriculus variegatus
Live California blackworms (Lumbriculus variegatus) are supplied in PE-bag cases. The supplier classifies the product under Feed for Fish > Live Food. Three case configurations are available.
Case options
One quantity means one complete case in the selected configuration.
| Option | Contents of one case | Combined labelled bag volume |
|---|---|---|
| 50 x 45ml | 50 PE bags, each labelled 45ml | 2,250ml |
| 25 x 90ml | 25 PE bags, each labelled 90ml | 2,250ml |
| 15 x 180ml | 15 PE bags, each labelled 180ml | 2,700ml |
The combined volumes are calculated from the labelled volume and bag count.
Product identity
| Common names | Blackworms, California blackworms |
|---|---|
| Scientific name | Lumbriculus variegatus |
| Animal group | Aquatic freshwater oligochaete worm |
| Format | Live worms in PE bags |
| Supplier category | Feed for Fish > Live Food |
| Sale unit | One complete case in the selected bag-volume and case-count configuration |
The label visible in the current product photograph identifies Lumbriculus variegatus. U.S. Fish & Wildlife Service and NCBI taxonomy records also recognise that scientific name for an aquatic oligochaete worm. Published aquaculture literature describes cultured L. variegatus as a source of live food for aquarium fish.
Choosing a case
All three options contain the same named live-food product. The practical difference is the size of each bag and the number of bags in the case.
| Configuration | Practical planning point |
|---|---|
| 50 x 45ml | The largest number of separate smaller bags |
| 25 x 90ml | Mid-sized bags; this is the format shown in the gallery |
| 15 x 180ml | Fewer, larger bags |
The option selector controls which complete configuration is added to the basket.
Supplier specification limits
The available product records do not provide a named-fish compatibility list, feeding amount or frequency, marine-fish use, complete-feed declaration, consumer storage temperature or shelf-life.
Gallery image
The gallery shows a labelled 90ml California blackworms PE bag, so it most directly represents the 25 x 90ml case option. It is not a photograph of a complete case or the other two bag sizes.

I have a small group of long finned mountain minnows. So was delighted to be able to order ten of this variety to increase the genetics in my tank . The ones I recieved are healthy but it’s to early to give a verdict on wether they are of a long finned type since they are small currently.

100% success travel and "installation". Pleased with quality of purchase. The Siamese fighter a bit "shy" so have not yet seen him at his best yet but looking good. Happy customer. GG
