Amphipod or Copepod
I've had my tank running for almost three weeks and today I noticed little critters running around on my rocks. Can't get a good luck at them so I'm not sure what they are. All i can see is what looks like scales on the back then they disappear into a crack or hole. Heading to the pet store tomorrow to get more live rock and maybe more sand. Plus getting a protein skimmer if they have any.
I'm still having issues keeping my sand from blowing around in the water column. Small tornadoes keep forming then sand blows into the water. I've tried my power heads in tons of different spots and combinations. Maybe more live rock will help.
