I have to algae eating shrimp (ghost/blue shrimp) and recently they stoped cleaning/eating. They are showing little movement and the algae is building up. I havnt fed them algae wafers in over 4days and they are still showing little movement. I am worried something could be wrong. Any imput would be appreciated.

Water Cond:

Ammonia: 0ppm
Nitrites: 0ppm
Nitrates: 5ppm
ph: 6.8-7


Thank you
