The Darwin Algae Shrimp is a very attractive small shrimp that needs to be kept with smaller non predatory fish. It is an ideal species for the consumption of algae in the planted aquarium. It will not eat blue-green algae but loves the filament hair type. A good number of these in the new planted aquarium is a help with keeping the algae at bay. After they have used up all the algae they will feed on normal fish foods. The female is larger with colour, males are small thin and clear. I have seen the colours range from light green to red with a white stripe running from the rostrum to the tip of the tail.

 

Lives quite well in fresh water and consumes algae and other detritus, good for clean up of unwanted food left overs. It does not reproduce very well in freshwater, however some juveniles do survive. There is no research for reproducing this species however it appears to be similar to some other Atyiid shrimps in that it needs a marine or brackish phase in its life cycle. To produce numbers of this shrimp its larvae are raised in brackish ponds with the salinity over 17 ppt with high DO levels and algae production via a good fertilisation schedule. Once the larvae are through their first few moults and resemble their parents they are changed over to fresh water.
