Although commonly reffered to as Caridina serrata, Tangerine tigers and Aura Blue are actually Caridina cantonensis according to Andreas Karge who had the microscope out for examination.
Aura blue:
One of my favourites. It has become more available and affordable and is really a stunning type. Very variable but with selection you can really get strong colours.
I keep mine at 250 µs/cm. but they have no problem in water up to at least 450 µs/cm.
Tangerine tiger:
Quite common in the hobby and inexpensive, but none the less a pretty shrimp! I keep mine in straight tapwater at 450 µs/cm. and pH 7,5.
Red tüpfel:
Probably a cantonensis-type, but not confirmed. Seems a slower breeder than the two above but very nice colour! I keep them in 250 µs/cm.
Hello,
SvarSletHello,
SvarSletMy tap water is around 75 µs/cm. What is the best way to raise it up to 250 µs/cm?
Thank you!
