NQ Algae Shrimp 'type 2' ( Caridina spp ) They eat hair algae, brush algae, most types of string algae, and are one of the few shrimp that will even eat black beard algae when no other food source is available. Very similar to Aust Amano Shrimp (they have the tendency to crawl out of tank during the first 24hrs when introduced).
Average size approx 3-3.5cm though sometimes they are smaller.
