Here is a description from the auction:
This prawn grows to 2-3 inches. The juvenile prawns look similar to a grass shrimp however, upon closer inspection, the back of the prawn has stripes like a tiger shrimp and the tail has red dots on each fin & the antennae & claws are red, white & blue when mature. These features become much more pronounced when adults. I think you'll be pleasantly surprised!, especially when the prawns mature into beautiful living gems. They are a beautiful clean-up crew, chowing hungrily on leftover flake and anything edible that sinks to the bottom. This prawn seems to get along well in a community tank. This prawn produces larval fry, and lots of them, regardless of salinity. Have a green water culture ready as i may send a berried female.
