Many of which have already been imported for the aquarium (see Sulawesi shrimps).
Kristina von Rintelen and Yixiong Cai published a revision of the lacustrine Caridina of Sulawesi in the most recent issue of the Raffles Bulletin of Zoology in which they describe these eight species.
The eight new species named are Caridina dennerli, C. glaubrechti, C. holthuisi, C. parvula, C. profundicola and C. striata from the Malili lake system, and C. caerulea and C. schenkeli from Lake Poso.
The authors also raise the concern the effect of collecting large numbers of lacustrine Sulawesi shrimps for the aquarium trade may have on the survival of these species.
The December issue of Practical Fishkeeping magazine includes pictures of the species and interview with Dr Kristina von Rintelen.
