Had my tank up and running for about 3 months. Unfortunately my tank got hit with marine velvet and wiped out all 6 of my fish. I’ve had the tank sitting fishless with only four hermit crabs and one emerald crab for about a week now. Just today I started to notice white spec on my glass moving through out the glass. Just curious on what they could be.
