Triops – the most famous primeval shrimps
Triops are among the best-known primeval shrimps. They are conspicuous for their large carapace, elongated abdomen, and two caudal filaments. Depending on the species, they differ in color, size, growth, and preferred rearing temperature, among other things.
In our Triops overview, you will find various species such as Triops longicaudatus, Triops cancriformis, Triops australiensis, and other special breeding forms. This allows you to compare the individual species and choose the appropriate breeding approach.

Fairy Shrimps – elegant swimmers without a carapace
Fairy Shrimps also belong to the primeval shrimps. Unlike Triops, they do not have a large carapace. They usually swim freely in the water, moving their many leaf-like legs uniformly.
There are various Fairy Shrimp species with different requirements for temperature and water. Therefore, always observe the information on the respective product page before breeding.
Clam Shrimps – special primeval shrimps with a shell
Clam Shrimps are also called Muschelschaler in German. Their body is surrounded by a bivalve shell, making them resemble small mussels at first glance. However, behind the shell are small crustaceans.
Clam Shrimps are an interesting addition for anyone who wants to learn about other primeval shrimp species in addition to Triops and Fairy Shrimps.
Primeval shrimps for beginners and families
For beginners, a complete Triops set is often particularly practical. Depending on the offer, it already contains important components for starting the rearing process. Always check exactly which components are included in the respective set before purchasing.
A complete set is particularly suitable for families, children under adult supervision, and anyone who doesn't want to search for every accessory part individually.
Buying primeval shrimps – which species suits you?
Before you buy primeval shrimps, you should consider which species best suits your capabilities and experience. Triops are particularly well-known and can be observed well during their rapid growth. Fairy Shrimps swim freely in the water, while Clam Shrimps have a completely different appearance due to their striking shell.
When choosing, pay particular attention to the recommended water temperature, the required tank size, and the information about the respective species. Not all primeval shrimps require exactly the same conditions. The specific instructions on the respective product page therefore always take precedence.
- Triops: large variety of species and particularly easy to observe

- Clam Shrimps: unusual crustaceans with a bivalve shell
- Complete sets: practical compilation for beginners
