Triops Granarius - primeval crayfish of the special kind
The Triops Granarius is native to Asia. In the meantime, however, the Granarius has colonized other continents, such as Africa and Europe. Most commonly, they are distributed in rice fields in Asia. Especially in Japan, this species is particularly common. In Europe they are very common in Italy. Thus, the Triops Granarius belongs to the Triopsarten, with the widest circulation areas. Although this prehistoric crab is very widespread in nature, it is considered exotic among hobby breeders because it is rarely sold in the market.
Triops Granarius - Reproduction and Development
The special feature of the Triops Granarius is that this Triopsart occurs gonochoristisch. This means nothing else than two-sexed, so males and females. The females lay only unfertilized eggs. Therefore, it is imperative that a male Granarius fertilizes them. When Triops Granarius pair, it seems like they are eating each other out at the beginning, but in fact the Triops mate. The proportion of Granarius males is significantly higher at 40% than in other types of Triops.
Triops Granarius - The Distinguishing Features of the Sexes
Visually, these animals are very nice to look at. Their color spectrum ranges from dark brown to beige. The males are often much lighter than the females and most of them have a very long tail. Another distinguishing feature is the carapace. This is slightly smaller in the males than in the females. Although this Asian Primeval Cancer is mostly on the ground, it is a very good and fast swimmer because of its long tail. Triops Granarius reach a size of 5 - 8 centimeters, including tail fork.
Triops Granarius - Living conditions for a species-appropriate attitude
It feels very comfortable at temperatures of 22 - 24° Celsius and can therefore be kept in the aquarium even at room temperature without a heating rod. This feature makes it very popular with breeders. The age is 8 - 12 weeks, depending on temperature and care. Of course, they should always have enough food and space to swim around. If the advice given is followed, cannibalism among them is extremely rare.
