Yesterday morning when I turnes on my light to start the day I noted tens of small white 1 mm "bugs" on the back of my tank, seeming to congregate where I have some stubborn algae growth. After awhile they disappeared but this am they were there again. Tank is about two months old, 14 gallon biocube w/ good live rock, 1.024 sg, pH8.2, 0 ammonia,0 nitrites, 0 nitrates, 77 degrees, 13 hermits, 2 arrows , 1 clown, 1 BTA(I know I need more light) . Are these copepods , do I need to do anything, Thanks
