Caridina multidentata, eggs and otos

^^amano shrimp (Caridina multidentata) and an otocinclus share a branch in the out-flow. Unfortunately, amano shrimp larvae, called zoe, need brackish water to develop.

^^unberried female, left, and male
^^the female fans her pleopods frequently to move oxygen rich water over the eggs
^^this boy is moving in a little too early. The female won't mate 
until her eggs have hatched and she undergoes a molt.
